SHORT TERM. /NEW/ Update: /Through Sunday Morning/
No significant changes to the forecast outside of minor tweaks for current trends this morning and mixing out western counties each day a bit more per slightly more veered winds and hotter temperatures. Winds should be light enough this afternoon to keep fire weather conditions low and no statement, despite above normal temperatures. Monday afternoon may be a different story, with breezy SSW winds near 15 mph, very hot temperatures around the century mark in advance of the long-anticipated cold front Tuesday, and fuel moisture/ERC-G values becoming more concerning by the day with lack of rainfall in the past month (as noted in the long term discussion below).
Otherwise, isolated showers and thunderstorms will be possible in our farther east tier of counties through sunset. No severe weather is expected.
Previous Discussion: /Through Tonight/
A broad upper trough continues to be anchored between the East Texas Piney Woods and Lower Mississippi Valley this morning. This feature will slowly lift northeast toward the Tennessee and Ohio Valleys by tonight. Meanwhile, impressive height falls occur across the Central/Northern Rockies/High Plains later today as a strong upper jet max of near 150 knots moves southward across the northern Great Basin and Rockies. This will result in shortwave ridging in advance of this impressive system and keep hot temperatures across North and Central Texas. Meanwhile, a diffuse area of high pressure at the surface will continue through mid afternoon, before lifting away from the area with increasing pressure falls occurring across Colorado/western Kansas by tonight. Light east or possibly northeast winds 5-10 mph look to become southeast around 10 mph later tonight.
Strong daytime heating will coincide with richer atmospheric moisture content and low inhibition across East Texas for the re- development of isolated showers and thunderstorms by afternoon. This won't be too different from what has been seen in the past few days. Fairly warm and stable mid levels will keep it all in the "garden variety" category. Most locales won't see any rainfall at all. The sparse convective activity across our East Texas areas will dissipate fairly readily after nightfall as strong diurnal heating comes to end and the upper trough to our east begins pulling away from our area.
The trend of above normal temperatures continues across the area for the tail end of your weekend with highs again mostly in the 90s (mid-September normals at DFW/Waco are in the upper 80s). The hottest conditions will be along and west of I-35, where deeper mixing, large scale subsidence, and plentiful insolation push this afternoon's highs to between 95 and 100 degrees. Morning lows both mornings will continue ranging between mid 60s and mid 70s under mainly clear skies.
LONG TERM. /Issued 349 AM CDT Sun Sep 19 2021/ /Monday Through Next Weekend/
Monday may turn out to be the warmest day of the month, with prefrontal downsloping winds pushing temperatures into the 90s by midday. Areas as far east as the I-35 corridor may reach the century mark, despite dew points in the mid 60s. In our East Texas counties, temperatures in the mid 90s will pair with dew points near 70F. In the far west, where shallower moisture will allow dew points to plunge into the 50s, the mercury may climb as high as 105F. It's across the Big Country, where some areas have gone over 30 days without a drop of rain, that fire weather concerns will be focused. However, weak mid-level flow should preclude a coherent dryline and would mean that deeper mixing may actually reduce the wind speeds at the surface. As a result, an enhanced potential for fire starts may be somewhat offset by the wind speeds, which may be insufficient to encourage fire spread.
Our highly anticipated cold front will enter North Texas before daybreak Tuesday morning. Moisture will have little time to recover in our northwest and western zones, which will miss out on the rain potential. Elsewhere, surface dew points will belie the shallow moisture depth, which may yield only a few showers and isolated storms coincident with the advancing boundary. Gusty north winds will make for a noticeably milder afternoon, even if temperatures are still in the 80s. The stronger cold advection will lag behind the front but will arrive in earnest Tuesday night when temperatures fall into the 50s and 60s.
With low humidity and noticeably cooler air on Wednesday, the autumnal equinox is perfectly timed. Wednesday night will be the coolest since last Spring, with the potential for a few low-lying spots in rural areas to dip into the 40s Thursday morning. A gradual warming trend will then commence, with afternoon highs returning to the upper 80s and lower 90s by next weekend.
AVIATION. /NEW/ Update: /12z TAFs/
No significant deviation from the 06z TAFs discussion below. The only addition was to add increasing S/SE winds later tomorrow evening, then especially after 13z Sunday, when lee-side cyclogenesis ahead of a Plains cold front drives sustained surface wind speeds (and gusts) up with breezy and hot conditions.
Previous Discussion: /06z TAFs/
VFR conditions prevail once again today, with the usual development of fair weather Cu with bases ranging between 050-080 kft. No weather concerns or flight restrictions are expected today for the D10 or Waco Regional Airport.
A broad low pressure trough aloft will remain far enough east of North and Central Texas terminals to keep isolated convection contained east of all terminals. At the surface, a weak and diffuse area of surface high pressure slowly shifts east by 00z Monday. Increasing pressure falls across the High Plains of CO/KS in advance of a deepening longwave upper trough over the Rockies will help E/NE surface winds between 4-7 knots become SE 7-10 knots by 06z Monday and beyond.
