SHORT TERM. /Issued 1149 AM CDT Mon Apr 19 2021/ /Today and Tomorrow/

A pleasant day is unfolding across North and Central Texas as high pressure continues to prevail. A surface high moved through the region last night and is currently moving into the Southeastern CONUS. Southwest winds, dry air, and abundant sunshine should allow temperatures to climb into the mid to upper 70s this afternoon despite the cool start to the day. One exception to this is over Central Texas where a stream of mid and upper level moisture continues to move overtop of the region. Some virga or even some faint sprinkles may fall out of this cloud deck, but should have little to no impact.

The surface high will continue to slide east tonight as a strong cold front, currently near the KS/OK border, barrels down the plains. Warm and moist advection will ensue locally ahead of the front and keep tonight's lows slightly warmer than this morning. Since this is the first night of return flow, the moist advection will be meager so no pre-frontal stratus is expected tonight.

An unseasonably strong cold front will approach Western North Texas around daybreak. The front should progressively march through all of North and Central Texas over the course of the day, clearing our southernmost counties in the early to mid afternoon. Heavily veered flow and limited moisture will keep the front dry with no precip expected despite some post frontal stratus developing. Tomorrow's temperature forecast is a challenge, but in general, expect the warmest temperatures of the day ahead of the front. There will be a temperature drop shortly after FROPA, however, insolation behind the front may allow some highs to occur in the afternoon where post-frontal stratus is thinner/more short lived. The front will also bring a sharp northerly wind shift with speeds around 15-20 mph and gusts generally around 30 mph.

LONG TERM. /NEW/ /Wednesday onward/

Broad cyclonic flow aloft continues across much of the CONUS today, and will set the stage for much below normal temperatures through the middle of the week. Morning surface analysis revealed a 1002 mb low over Lake Superior with a cold front extending southwest along a line from Milwaukee to Kansas City to Great Bend, then extending northwest towards a 1011 mb surface low centered near Preston, Idaho. Ahead of this cold front, the southern and eastern portions of the CONUS are ensconced within a continental polar air mass, with continental Arctic air to the north of the front. As of 12Z this morning, the freezing line extended as far south as the I-80 corridor across Nebraska and Iowa, with strong cold air advection underway behind the cold front.

This cold front is forecast to arrive in North Texas on Tuesday morning (see short-term discussion), with much cooler air overspreading the region following FROPA. Morning lows on Wednesday will drop into the 30s across much of the FWD CWA, with a light freeze forecast for areas north and west of the Dallas/Fort Worth Metropolitan Area. Given the very late nature of these expected freezing temperatures, a Freeze Watch is in effect for these locations, and it is probable that this will be upgraded to a warning within the next 24 hours. To the south of this area, patchy frost, which can be just as dangerous to sensitive vegetation as below freezing temperatures, is expected. Frost appears likely as far south as an Athens to Waco to Goldthwaite line. A Frost Advisory will likely be needed for these locations, but we will wait until it is a little closer to the event to issue any headlines, and in the meantime, further refine the areas and specific impacts.

Southerly flow should return by Thursday as the surface high pressure moves off to the east and an upper-level trough digs into the West Coast. This upper-level trough will approach our region by Friday, leading to lee cyclogenesis, and in return acting to strengthen low-level warm air/moisture advection, setting the stage for a potential severe weather episode. SPC has drawn much of the FWD CWA within a 15% risk area for severe weather given that instability looks to build within the warm sector, with strong upper-level wind shear forecast as well. There remain some differences between models (in terms of both individual models, and run-to-run consistency). For this reason, have opted to indicate Likely PoPs during the day Friday as well as Friday night, though this will likely need to be refined as the event approaches.

Heading into next weekend, upper-level ridging will build across the south-central CONUS. There is a wide spread in individual models with regards to how much we will warm in response to this ridging, but near to above normal temperatures appear probable, along with dry conditions.

AVIATION. /Issued 1149 AM CDT Mon Apr 19 2021/ /18Z TAFs/

VFR and light southerly winds will continue today and tonight. A stream of mid level clouds over Central Texas may produce some virga INVOF KACT/KGRK, but should have little operational impact. A cold front will move through tomorrow with FROPA expected at the D10 terminals between ~15-17Z and ~17-19Z for KACT. Expect a sharp northerly wind shift with FROPA and gusty north winds/VFR stratus continuing for much of the day tomorrow. There is about a 20% chance the stratus will be high end MVFR at times, but confidence of this is too low to include in the TAFs ATTM.
