Nice Summer pattern for us with surface high pressure to our east and rising heights aloft. Our KSHV VAD winds are getting nice deep SE flow up into the midlevels, compared to a more easterly flow earlier today noted on our 12Z sounding. Even the freezing level is up to 14.5kft this morning. We have broad, scattered to broken Cu field areawide with bases up near an inversion at 6kft. This pattern will continue again to start the new week and even linger into Tuesday as the upper ridging refocuses over the lower MS River valley. Of course, this will keep our air temps well above average for mid to late May, where mid 60s and mid 80s are the "norm". It was 88 at noon in TXK and SHV today with 92/93 respectively so far. However, now that the cu field is going broken over NW LA and we may be done there. The overnight will see skies become fair with a touch of patchy fog with the overall the soil moisture on decline. And it looks like the lower 90s will persist all week, especially along and south of I-20. /24/

The upper ridging will spread it's axis over the SE U.S. this week, but remain anchored over Mexico at 594dam. The long wave pattern over the western U.S. along with a few core lows will consolidate over the front range with a tightening gradient and a single core low at 555dam just north of the 4 corners. This will be generating and sending short wave energy around in the deep pattern. This coupled with a much better return flow off the Gulf that will develop for us with the first short wave nudging over the OK/TX panhandles Tuesday late with a chance for some convection to work into our I-30 corridor overnight.
It all comes together with much better TS coverage which will unfold during midweek with the storm track off the front range focused on the plains and eventually middle MS River valley, but still close enough to allow convection to persist, both nocturnally and diurnally to wrap up the work week. The Storm Prediction Center has a Slight Risk look on their days 4 and especially day 5 blanketing a good portion of our area. And the Weather Prediction Center highlights our northern half with Slight and Marginal Risks in the days 4/5 EROs on Wednesday late and again on Thursday into early Friday.
A little bubble surface high at 1017mb will be quite sufficient to bottle up and pool moisture during midweek for us and again late week replaced by a 1014mb air mass riding over the mid MS River valley. These coupled with convective forcing with cool pooling and of course daytime heating will bring a good scattering of convection our way and perhaps see even numerous coverage at times, mainly north of I-20. However, no wind shifts for us with the summer-like readings edging back a bit to upper 80s across our north anyway with the added clouds. For those looking farther ahead, a third surface ridge will be much stronger at 1024mb over the plains early next week, so we should keep at least isolated activity going this weekend, with a renewed focus for ArkLaTex convection just after the holiday weekend to top off our already very full May rain buckets. /24/
AVIATION
(18Z TAFS)
Issued at 1242 PM CDT Sun May 19 2024
For the 19/18Z TAF period, VFR conditions are expected through the period with just some fair weather cumulus averaging around 5Kft this afternoon. Mostly SKC conditions are expected overnight with a few instances of patchy fog possible, but aviation impacts are not likely. Otherwise, light E/SE winds will persist around 5 kts or less today and tonight, increasing from the S/SE on Monday to between 6-12 kts. /19/
