UPDATE. Issued at 936 PM CDT Thu Apr 15 2021
Have issued an update to lower the evening POPs a little out west to give a little more separation between the waves of precipitation. Although with the echoes developing in west central and southwest, it won't necessarily be a complete shut off before the next wave expands, but it's work lowering evening POPs a little in the west as it won't be as widespread as we've seen earlier this evening.
SHORT TERM. (Today and tonight) Issued at 237 AM CDT Fri Apr 16 2021
Moist isentropic lift is expected through the early morning Friday (today). This will likely lead to generally increasing areas and intensities of rain. Modest amounts of elevated instability are expected aloft, so elevated thunderstorms are similarly expected. With a warm/humid vertical profile up to the freezing level at around 10,000 ft, hail will have a difficult time making it to the ground, but will still be possible, given the amount of instability (up to about 1,000 kJ in our southern counties) and wind shear.
The upper-level wave that is generating the lift and shear will trek east across Kansas today, and as it moves off to the east, its support for precipitation and convection will diminish. Rain chances will diminish from west to east with the progression of the wave.
With widespread cloudiness through most of the day, afternoon temperatures over most of our forecast area will remain well below average. Partial clearing is expected late tonight over the west, which will allow temperature to drop to near freezing in the far northwest.
LONG TERM. (Saturday through Thursday) Issued at 218 AM CDT Fri Apr 16 2021
Gusty north winds after a cold front on Saturday will diminish somewhat on Sunday while the surface high moves into Oklahoma Sunday. An upper short-wave trough in the northern-more branch of the westerlies will move southeastward through the central plains brining a cold front and cool airmass into Oklahoma Monday evening and early Tuesday. Limited moisture with this system will keep pops brief and low for rain/snow in northwestern Oklahoma early Tuesday. This will be a fairly cool air mass for late April with gusty winds and afternoon temperatures in the 50s with some 30s at night. The next chance for rain comes Thursday with above-surface moisture arriving through the TX/OK panhandles early Thursday and and short- wave trough approaching in the northerly branch of the upper flow.
AVIATION. (12Z TAFS) Issued at 626 AM CDT Fri Apr 16 2021
An area of TSRA will move east early this morning from near KPNC- KOKC-E/KSPS at 12Z to near the Oklahoma/Arkansas border by 16Z. Behind the TSRA, expect low clouds and areas of drizzle. As the related storm system moves east this evening, subsidence aloft should erode most of the clouds from west to east . but the most believable model forecasts bring low clouds (ceilings around 1000 to 2000 ft) back to much of central/western Oklahoma and the KSPS area early Saturday morning. At KPNC and KSWO, it looks like the MVFR/IFR-level ceilings will not relent through the TAF period.
