SHORT TERM. /NEW/ /Through Tonight/

The Freeze Warning has panned out swimmingly so far with numerous locations in North Texas having fallen to freezing or just below over the past few hours. These sites include Gainesville, Bowie, Bonham, Sherman, Denton, McKinney, Bridgeport, Breckenridge, and Eastland. A few others (such as Paris and Mineral Wells) could still jump on the 32F bandwagon in the next hour or so. The rest of the CWA will largely begin the day with readings in the mid or upper 30s with some frost possible across a majority of the area. Both DFW and Waco have already set new daily record lows for April 21st, and their values may still fall lower prior to sunrise.

Following the cold start to the day, insolation in the presence of dry air will allow highs to warm into the 60s, but these values are still about 15 degrees below normal for this calendar date. An increase in mid/high cloud cover is expected later this morning and into the afternoon as a few separate cloud decks expand ahead of a deepening upper trough positioned far to our west. Despite the increased ascent and mid-level saturation, no precipitation is expected to fall from these cloud layers due to very dry sub- cloud air. As surface high pressure translates east later in the evening, an east/southeast wind will resume. When combined with increased cloud cover, tonight's lows should be significantly warmer, mainly in the 40s heading into Thursday.

LONG TERM. /Issued 303 AM CDT Wed Apr 21 2021/ /Thursday and Beyond/

Return flow will commence on Thursday as surface high pressure slides southeast into the Mississippi Valley. North and Central Texas will still be covered by a fairly cool airmass, however, as yesterday's front will be stationary and situated over the Gulf and South Texas. Though warmer than this morning, temperatures will be in the 40s at the start of the day with readings warming into the 50s and 60s in the afternoon.

The front will retreat north as a warm front Thursday afternoon through Thursday night as a shortwave trough over the Desert Southwest advances eastward towards the region. The resulting warm advection regime may lead to scattered light showers Thursday night, but a fairly stout EML should preclude convective development for the most part. That said, steepening mid level lapse rates along with a strengthening low level jet may kick off a few elevated storms after midnight, though these would likely remain isolated and sub-severe.

Further intensification of the warm/moist advection regime is expected early Friday as the shortwave enters West Texas and a surface cyclone deepens over Northwest Texas. The warm front will likely enter Central Texas by midday, bringing a surge of mid and upper 60s dewpoints along with it. Further west, a dryline located across the Big Country will surge east into the western zones as the shortwave disturbance and attendant surface low shift east along the Red River.

Convective initiation looks likely early to mid Friday afternoon along either the warm front or dryline, and instability along with deep layer shear should be sufficient for a severe weather risk, particularly if any discrete cells occur. A limiting factor may exist if storms get going too early (mid to late morning). This could affect shear profiles and instability later in the afternoon when things would otherwise be more ideal for severe storms to occur. Either way it looks like at least a low-end severe threat will exist with both damaging wind gusts and large hail possible, and any storms in the vicinity of one of the surface boundaries would need to be closely monitored for a possible tornado threat.

The best rain and storm chances will be along and east of I-35 where the deeper moisture will exist, but it is still a bit uncertain on exactly when and subsequently where storms will first develop. We should get these and other details ironed out as we start to get within about a 48 hour window of the event, and even more-so, 24 hours within we expect the convective event unfold.

Activity will spread east and should all be east of I-35 by sunset as a cold front overtakes the dryline, and then all storms will shift east of the region at or shortly after midnight. Though a cold front will push through, it will likely be followed by warmer days as the shortwave races off to the east and a strong ridge develops overhead in its wake. Highs in the 70s and 80s are expected over the weekend with a few readings near 90 possible across the west both Sunday and Monday. The upper level pattern will remain progressive next week, with the ridge exiting east and the next trough bringing more chances for showers and storms Tuesday and next Wednesday.

AVIATION. /NEW/ /12z TAFs/

A light northeast wind will prevail today before an eventual return to east/southeast winds later this evening. While predominantly SKC conditions currently exist, a couple of mid/high cloud decks will expand across the area later this morning. Mid-level cloud cover around 10 kft should become increasingly dense across North Texas, while cirrus closer to FL250 should be more prevalent across Central Texas. Each area could begin seeing VFR cigs closer to 6-8 kft by late afternoon or evening. BKN/OVC VFR skies should then persist into Thursday morning with a southeast wind.
