.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.
