AVIATION. /12z TAFs/
The main concern through this TAF cycle is the potential for visibility reductions, both this morning and again Sunday morning.
Patchy mist/fog has developed due to clear skies and light winds, and is occasionally reducing visibility at TAF sites to as low as 3-4SM. However, these conditions should be relatively short-lived as light winds become more northwesterly, allowing slightly drier near-surface air to filter into the area. Have maintained Tempo groups for MVFR visibility for a couple more hours. Later this morning, winds will gradually return to the east and southeast while remaining less than 10 kts.
The return of southeasterly flow will usher in a warm front Sunday morning, with ample low-level moisture spreading into a cool airmass already in place. This should result in fairly widespread fog, some of which may be dense. Have introduced reduced visibility at all TAF sites for Sunday morning beginning around 09-10z, but my current advertisement of 4SM is probably too optimistic. Visibility of a mile or less seems likely for at least a couple hours at most TAF sites. This will need to be monitored for upcoming TAF issuances.
SHORT TERM. /Issued 258 AM CST Sat Dec 14 2019/ /Through Tonight/
A weak cold front was draped from roughly Tulsa to Wichita Falls as of 3 AM, and has been making slow southward progress into North Texas. Just ahead of the boundary, calm winds and clear skies have allowed temperatures to approach dewpoints, resulting in the development of patchy radiation fog. Moderate northerly 925mb flow along with the eventual arrival of slightly drier post-frontal air should prevent much in the way of dense fog from being able to develop this morning, but we'll have to keep an eye on the potential necessity of any fog headlines through daybreak across the eastern half of the forecast area. Other than acting to clear the visibility reductions, the cold front will mostly go unnoticed from a sensible weather standpoint.
Otherwise, it's shaping up to be a pleasant Saturday with highs mostly in the 60s or low 70s. A small increase in cirrus can be expected across North Texas, but otherwise skies will remain relatively clear. Later tonight, low-level flow will quickly turn around to the southeast following this morning's front, and a warm frontal feature will move northward early Sunday morning. This will be favorable for advection fog to develop as higher dewpoints encounter the cool temperatures that will be in place. This fog could be rather widespread, and some may be dense as well. Areas of fog have been introduced to the forecast for tomorrow morning, and will be refined with subsequent forecasts.
LONG TERM. /Issued 258 AM CST Sat Dec 14 2019/ /Sunday through Next Weekend/
A warm air advection regime will be ongoing at the start of the period ahead of an approaching shortwave trough and surface frontal system. Areas of fog and perhaps drizzle will be a good possibility as higher dewpoints enter from the south and overspread a chilly airmass, primarily south of the Interstate 20 corridor. Winds will be out of the south for most of the area during the day, but veering winds will become likely across the western counties as the front approaches from the northwest. Downslope flow will result in well-above normal temperatures along and west of I-35/south of I-20, where highs may top at or above 80 degrees. The high temperature forecast becomes a bit more tricky for counties along the Red River, because it is possible that the front creeps into the area during the mid to late afternoon hours, which would hold temperature's in the 50s. Chances are, however, that readings will climb into the lower 60s across the north prior to the arrival of the frontal boundary.
The trough will deepen while dropping southeast into Northwest Texas Monday night, with the front subsequently surging south through the region. Despite the warm/moist advection ahead of the system, this pattern will have been short-lived and moisture return minimal. Scattered showers will become possible along the front, but likely will not develop until the boundary is over the southeastern half of the forecast area. Similar POPs to the previous forecasts will be used for this forecast package, if not slightly lower, with the best rain chances along a Paris-Palestine line and areas east.
A seasonably cold airmass will engulf the entire area as the front heads for the Mississippi Valley and Gulf of Mexico on Monday. High temperatures in the 40s and 50s can be expected Monday and Tuesday with sub-freezing conditions occurring during the overnight hours. The coldest night still looks to be Tuesday night when ideal radiative cooling conditions will develop, and the current forecast will indicate readings dropping mainly into the 25 to 30 degree range by daybreak Wednesday.
A slight warming trend will begin during the day Wednesday as return flow begins in advance of the next upper level trough and surface front. This system is progged to pass eastward through the Southern Plains late Thursday or Friday. Good ascent will accompany the trough, but moisture will once again be the mitigating factor regarding precipitation potential. Low-end rain chances will continue for areas along and east of I-35 Thursday night through Friday night. Dry conditions and above-normal temperatures then look likely as upper level ridging builds overhead next weekend.
