Area forecast discussion, Apr 12, 3:15 AM CDT, 21 minutes before
Area Forecast Discussion National Weather Service San Angelo TX 315 AM CDT Sun Apr 12 2020 .SHORT TERM... (Today and Tonight) Scattered to numerous showers and thunderstorms will continue through the early morning hours, with most of the activity moving east of the area by daybreak as a Pacific cold front moves across the region. West winds will increase to 15 to 25 mph, with higher gusts, by mid to late morning. Highs today will be in the upper 70s to lower 80s. A strong cold front will move into the Big Country by mid to late afternoon, eventually making it to Interstate 10 by mid evening. Gusty north winds of 15 to 20 mph along with much colder temperatures can be expected behind the front. Overnight low temperatures will be in the mid to upper 30s for most locations. Wind chill values by sunrise will be in the mid 20s to lower 30s, which will be a significant change from todays temperatures. .LONG TERM... (Monday through Saturday) Much cooler weather expected Monday and Tuesday as post-frontal cold air advection occurs from the northeast and surface high pressure builds into the region. Expect highs Monday and Tuesday only in the low to mid 50s in the Big Country, upper 50s/low 60s in the Concho Valley/Heartland, and low to mid 60s in the I-10 corridor. With mostly clear skies and weak winds Monday night and Tuesday night, radiational cooling will be enhanced, allowing lows to fall into the low to mid 30s in the Big Country, and mid to upper 30s elsewhere. Southerly low level flow returns during the day Wednesday as a surface and 850 mb ridge moves to our east, which should allow for some warming, with highs in the low to upper 60s, and lows Wednesday night in the low to mid 40s. More significant warming expected Thursday as warm south flow continues and the 850 mb thermal ridge strengthens. Expect highs Thursday in the mid to upper 70s. Another cold front may move through on Friday, but it doesn't appear strong enough to bring much of a cool down at the moment. Another upper level trough will approach from the west on Saturday, with the GFS deeper and wetter than the ECMWF which doesn't show much of any rain. Am keeping the forecast dry for now, except for our extreme eastern counties where a slight chance of thunderstorms exists. && .PRELIMINARY POINT TEMPS/POPS...
