Area Forecast Discussion National Weather Service Fort Worth TX 605 PM CST Mon Nov 23 2020 ...New Short Term, Aviation... .SHORT TERM... /NEW/ Update: Low level warm air advection will continue overnight into Tuesday with extensive clouds, patchy drizzle and increasing rain/ thunderstorm chances Tuesday. The current forecast on track, see previous discussion below for details. 79 Previous Discussion: /Today and Tomorrow/ Yesterday's cold front has brought much cooler temperatures to the region. The depth of the cold air is pretty shallow which has allowed for widespread cloud cover to remain in place and/or develop this morning. This should inhibit insolation and keep temperatures from climbing too much this afternoon, with most of us struggling to get into the low 60s. The exceptions to this are over North East Texas and over the Big Country/Western Central Texas where slugs of low level dry air has helped scour the dense stratus. Warm and moist advection will start to move overtop of Central Texas late this afternoon then North Texas tonight. Another night of widespread stratus is expected as warm and moist air continues to move overtop of the cooler near surface airmass. Meanwhile, a leeside low should deepen through the night and help develop a 35-45 kt low level jet aloft. This will allow for weak isentropic ascent to persist, increasing when a weak shortwave trough moves overtop of the region. This will help develop scattered sprinkles and/or light rain showers in the pre-dawn hours. No thunder is expected in the overnight period as the strongest forced ascent brushes by to our northwest. Tomorrow will be warmer than today and breezy as we reside firmly in the open warm sector of the aformentioned leeside low. Warm advection looks to be pretty strong with a 45-50 kt low level jet that maintains itself through the day. We expect scattered showers in the morning which may evolve into a few warm-advection storms in the afternoon. Veered low level flow should keep most of this activity east of I-35(E) late in the morning and through the afternoon. There should be some surface based instability present, however, most of the activity should be elevated and rooted around 900mb. If storms are able to tap into the surface parcels in the late afternoon, a few strong wind gusts would be possible. Outside of precip, it should be a pretty breezy day with south winds 10-15 mph and gusts to 25-30 mph. If the cloud cover is able to break apart, occasional wind gusts upwards of 40 mph are possible. Bonnette && .LONG TERM... /Issued 318 PM CST Mon Nov 23 2020/ /Tuesday night through next Monday/ Rain and storm chances will continue to increase and expand Tuesday night ahead of the approaching cold front. Most of the activity is expected to remain scattered through the early evening hours before it merges into a cluster/line along the front later in the night. While the best rain/storm chances continues to be across the east and southeast counties, some of the latest CAMs are now developing this line as far west/north as near the DFW Metroplex (near the I-35 corridor). There should be enough instability, moisture, and lift for these showers/storms to organize, but due to model discrepancies we kept PoPs in the 40-60% range. We can't rule out a severe wind gust or hail with this activity, but we expect that the best potential will remain north of our area. Rain chances will quickly end as the front exit the southern counties early Wednesday morning. Plenty of sunshine, light winds and cooler temps are in the forecast for Wednesday, with highs mainly in the 60s. Thanksgiving Day looks pretty nice for outdoor activities. The forecast shows mostly clear skies, breezy south winds, and temps that will range from the upper 60s across the northeast to 70s elsewhere. The next cold front is set to arrive on Friday. A few showers and storms may develop as early as Friday morning, but the best rain/storm chances will be Friday afternoon/evening across the southeast as the front encounters better moisture. Model guidance continues to diverge beyond Friday night and into the weekend. The ECMWF depicts a slower progression of an upper low, versus the GFS's faster progression and drier solution. As expected, ensembles are also showing these uncertainties, flipping between a wet or a dry weekend. Until we get better agreement, we will keep mentioning a chance of PoPs areawide at least into Sunday. Otherwise, it appears that temperatures will stay in the cooler side with highs in the 50s/60s and overnight lows in the mid 30s to 40s. Stay tuned! Sanchez && .AVIATION... /NEW/ /00Z TAFs/ MVFR ceilings have lingered through the afternoon in a narrow band about 45 miles east and west of I-35. A brief scattering of this deck is possible around 02Z/03Z, but low ceilings will return later this evening when a 35+ knot low level jet sets up in response to deepening surface low pressure across the Central High Plains. Low end MVFR ceilings will likely develop in the predawn hours Tuesday, followed by IFR ceilings after sunrise. These low ceilings will be slow to lift but should improve above 1000 ft in the afternoon. VFR conditions are expected by late afternoon once drier air associated with a pre-frontal trough begins to work in from the west. The only other concern in this TAF package will be the chance for thunderstorms Tuesday evening with the arrival of a deep shortwave and associated cold front. Storms will likely organize along the front, impacting the Metroplex TAF sites roughly from 02-05Z Tuesday evening. Therefore, we will include the mention of thunder in the vicinity in the extended portion of the DFW TAF. A southeast wind between 8 and 13 knots this evening will become more southerly Tuesday with wind speeds increasing between 13 and 17 knots along with some gusts near 30 knots. Wind speeds should decrease slightly late Tuesday afternoon ahead of the approaching cold front. 79 && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.
