Arial view of supercell storm over SW Texas (flight was from Phoenix, Arizona to Fort Lauderdale, Florida at about 38,000 feet in a Boeing 737-700). The view is looking N and the storm is roughly 100 miles away just before 8 PM CDT. A weak tornado and giant hail occurred with this storm on April 29, 2019 and was the first in a series of severe storms and tornadoes over the central USA over a few days in the central USA.

Posted: Apr 30, 2019, 6:57 PM

SW Texas supercell (from B-737 airliner on 4/29/2019). Note the twin RFD cuts in the updraft to the left (storm cycling with new mesocyclone developing to the east / right). Impressive inflow bands from right to left. Note the "left split" smaller storm under the anvil to the right of the main storm.

Looking towards the west from south of Wayside, Texas, the incredible streamwise vorticity current along the supercell FFD (forward flank downdraft) screams from right to left into the main updraft. The horizontal tube, or "rotor", is marked by ground scraping low clouds as it is pulled into the storm as it cycles up again late on May 7.

Posted: May 13, 2019, 10:44 AM

View of approaching HP supercell with the late states of a wedge tornado near Tulia, Texas on May 7 at roughly 5:45 PM CDT. The view, taken from south of Wayside, is to the southwest and directly into the HP "notch" of the supercell, and between the wet RFD (to the far left), and forward flank precipitation (to the right).

This is the backside of the upper level disturbance, marked by high clouds, as I continue east into New Mexico near Albuquerque on May 7. This wave is racing east and will provide important upper level support for severe weather later on in the Texas Panhandle.

Posted: May 13, 2019, 10:44 AM

The sky becomes rather bizarre with asperatus looking clouds as the axis of the upper trough is crossed as I continue east on I-40 across eastern New Mexico and approaching the Texas border on May 7. This is due to turbulence and large scale ascent associated with the exit region of the upper wave.

May 18 was a chase day involving a reposition down south to catch some storms in recovering air well behind a large MCS. In the left image, the SPC tornado probabilities are shown based on their 1630z enhanced risk outlook. The large 10% significant tornado threat over the Arklatex region was mainly for embedded supercell structures and vortices within a line of thunderstorms, and over poor chase terrain / forested areas, and not much of interest in a storm chasing manner. The smaller 5% risk area, accompanied by a 15% wind and 30% significant hail threat, was the objective area for today's chase. The middle image is the SPC Mesoscale Discussion 671 issued as well as subsequent severe thunderstorm watch box 186, valid until 10 PM CDT.

Posted: May 19, 2019, 4:39 PM

This is an annotated visible satellite image at roughly 23z showing the storms and environment unfolding over NW Oklahoma during airmass recovery at roughly 23z on May 18, 2019. Note the small supercell storms developing at the intersection of the dryline and stationary front. The MCS to the east was not of interest to storm chasing operations this day since it was over poor terrain with trees, as well as any tornadoes being embedded within the line of storms.

Posted: May 19, 2019, 4:39 PM

This is an annotated visible satellite image at roughly 23z showing the storms and environment unfolding over SW Nebraska and NW Kansas on May 17, 2019. Note the main supercell of interest at the southern most area in the convective activity, which is also the same cyclic supercell that affected areas from McCook, Nebraska and northward on May 19.

Posted: May 19, 2019, 4:39 PM

May 17 was a major and complex chase day in southwest Nebraska. In the image above, the SPC tornado outlook is shown (within an enhanced risk as of their 13z outlook). The main target area was in Nebraska with a 10% (significant) tornado threat. Another area was also in SW Texas. Both of these areas produced tornadoes, including areas just south of the northern target. In the middle image, Mesoscale Discussion 649 is shown, and subsequent tornado watch box 172 to the right, valid until 10 PM CDT (9 PM MDT).

Posted: May 19, 2019, 4:39 PM

May 16 was a marginal chase day as well as a travel day to west-central Nebraska. The western end of a slight risk (as of 20z) was targeted with both up-slope wind flow and weak low pressure impinging into the Nebraska Panhandle from the west. The slight risk also had a highly conditional 2% tornado probability, and is annotated in the left image above. The middle image shows the Mesoscale Discussion 639 issued by the SPC. To the right is an annotated visible satellite image of the setup, showing small supercell storms firing over the Nebraska panhandle.

May 27 was a better chase day, with a nice post-frontal / up-slope setup in northeastern Colorado, with some tornadoes observed and not plagued by storms developing before even finishing lunch! In the left image above, the SPC had two enhanced risk outlooks, one over NE Colorado, and another way east and out of reach near Illinois. In the image, the tornado probabilities are shown as per the 13z SPC outlook, with the objective target area pointed out in the 5% area. The 10% significant far and distant tornado risk area to the east (northern Illinois) was not applicable for this chase day. The middle image shows Mesoscale Discussion 833 for the main target area. Tornado watch box 264, valid until 9 PM MDT is shown to the right.

Posted: Jun 3, 2019, 11:03 AM

May 26 was another "moderate risk" chase day that really panned out as a grave disappointment, due to poor air quality (stable air) from expansive early morning convection persisting over Texas from the night before. In the image above, the SPC has a moderate risk in place as per 1630z, with the 15% hatched (significant) tornado area shown to the left. The middle image is Mesoscale Discussion 810 as well as subsequent tornado watch box 253, valid until 9 PM MDT (10 PM CDT) to the right.

Posted: Jun 3, 2019, 11:03 AM

May 28 was a frustrating chase day with multiple targets requiring no "hesitation" once storms developed. The primary target area was from Topeka and eastward. In the SPC image to the left, a 10% tornado outlook is shown as per their 1630z moderate risk outlook. The middle image is Mesoscale Discussion 853. To the right are tornado watch boxes 275 and 276, both valid until 10 PM CDT. Hesitant decisions and straying too far from my target area caused me to miss tornadoes today.

Posted: Jun 3, 2019, 11:03 AM

May 29 was both a marginal chase day and travel day, since I was already en-route to Chicago for down time during the succeeding days. Despite a large enhanced area to the far south and east (with a 10% tornado area in SE Texas and well out of reach), I decided on the "cold-core" setup in eastern Iowa, which had a 2% tornado outlook as per SPC at 1630z. The tornado probabilities and my target area are shown to the left. Both produced significant tornadoes. The middle image shows Mesoscale Discussion 882 for the far and distant SE Texas target. To the right, is Mesoscale Discussion 885 for my area targeted in eastern Iowa (no watch was issued there).

June 23 was another seemingly good chase day that turned out to be only outflow dominant / squall line type storms in north-central Texas. In the images above, the 13z SPC outlook is shown, with an enhanced risk and my target area annotated. A 5% tornado probability is indicated as well in the lower left inset. In the middle and right images, is Mesoscale Discussion 1216 and severe thunderstorm watch box 436, valid until 10 PM CDT, respectively.

June 25 was one of the last chase days of this chase segment, with activity observed in south-central to SE Nebraska. As many chases before on this trip, an enhanced area was issued by the SPC at 1630z, and is shown in the left image above. A 5% tornado probability is also shown, and my target area is annotated. In the middle and right images is Mesoscale Discussion 1243 and severe thunderstorm watch 444 valid until 10 PM CDT, respectively.

June 26 was a travel day wrapping up this chase trip segment with a drive to spend some time in Chicago. At the end of the day, a severe thunderstorm was intercepted late the day in the western Chicago suburbs. In the images above, the 13z SPC outlook is shown to the left, showing a large slight risk area over the northern Plains and a separate more conditional slight risk over Illinois. The "impromptu" target area is denoted by the annotation in the left image. No Mesoscale Discussions nor watch boxes were valid for this area as per SPC. The middle image shows a visible satellite image of my area of interest near 23z and is annotated showing important features. Note the large MCS of strong thunderstorms ahead of an MCV (mesoscale convective vortex) extending across the Saint Louis area. To the far north are some transient supercell storms causing severe weather over northern Illinois, one of which I observed this day. The right image above is a base reflectivity image out of Chicago, showing a prominent "hook" and intense precipitation core (large hail) as the storm was over the western Chicago suburbs (my indicator is the blue cross hairs). No tornadoes were produced by this storm (mainly large hail and high winds).

While staying in the Chicago area, I managed to get the rear window of the chase vehicle replaced (damaged from the June 21 storm near NE Colorado / W Kansas).

While beginning the long drive back to California and passing through Nebraska on I-80, a distant supercell can be seen looming over the horizon on a confluence axis late in the day on July 8. The storm is to the lower right and is roughly 40 miles away and developing along a confluence axis oriented NW to SE. A very brief tornado was reported with this storm. The view is to the southwest.

It was an awesome pleasure meeting up with Dr Jason Persoff, left, and veteran chaser Dave Hoadley, right, literally "under the meso" while headed back east to the northwest of Limon, Colorado late in the day on June 21. Thanks to Dave Hoadley for sharing this picture of myself (center) and us! Dave has been out chasing more (and longer) than any other storm chaser to this day.

Dust, hail, and small rocks are kicked up in two powerful micro-bursts (the first being dry, and the second loaded with rocks and hail) at a gas station in Sharon Springs, Kansas after dusk on June 21. The second "derecho" surge of straight-line winds gusted near 100 MPH blowing out windows on many vehicles parked at the gas station. The rear window on my Jeep was blown out from the sand / rocks, with even the screen on my phone, mounted on the dash board, broken! Rocks and sand were all over my vehicle, and the front window was cracked and mirrors pitted.
