SHORT TERM
(Today through Monday)
Issued at 229 AM CDT Sun Apr 21 2024

A weakening upper level shortwave currently moving over our area is producing showers and storms ahead of it, mainly along and east of the I-35 corridor. This feature will move east of our area by sunrise ending the showers and storms as subsidence takes hold due to upper level ridging building over our area today through Monday. Cold advection along with widespread cloudiness and breezy northeasterly winds will make for quite a chilly day by late April standards.
Clouds erode or thin tonight into Monday. This allows for a cooler night tonight due to decreasing winds and a warmer day on Monday as cold advection ends and southerly winds return. Well below normal temperatures are expected today through Monday.

LONG TERM
(Monday night through Saturday)
Issued at 229 AM CDT Sun Apr 21 2024

The beginning of the long-term portion of the forecast is expected to be dry as weak ridging moves in place over the region. Highs on Tuesday will top out in the upper 70s to lower 80s for most locations but will warm into the 80s areawide on Wednesday. The upper ridging will give way to the next approaching upper trough axis by Thursday. The base of this trough will pass to our north, but some of the medium range models are showing some low amounts of QPF within the southerly flow ahead of the trough on Thursday and Friday. This would most likely be just some showery activity underneath a stoup capping inversion expected to be in place. The official forecast will show just some 20 PoPs in the northern counties in closer proximity to the best lift. Highs Thursday and Friday will be in the 80s to lower 90s. Behind the system, even warmer conditions are expected on Saturday with highs in the upper 80s to upper 90s with the warmer values expected towards the Rio Grande. Besides the low rain chances on Thursday and Friday, no impactful weather is expected during the long-term portion of the forecast.
