KEY MESSAGES

Updated at 1258 PM CST Sun Nov 8 2026

- Wet, dreary, and cool weather continues Today and Monday

- Embedded heavier rain and storms to be expected at times resulting in a low risk for isolated flooding.

- Drying out some with milder temperatures mid to late week.

SHORT TERM

(Tonight through Monday night) Issued at 1258 PM CST Sun Nov 8 2026

Widespread rain is currently ongoing across the area as the upper level low continues to advance closer and closer. Thus we should see the most widespread and best chances of rain occur this afternoon with a lull then expected by this evening across our northern and eastern areas including the Austin metro before we see another round of rain form over the Rio Grande and Southern Edwards Plateau areas. This 2nd round should continue pushing eastward late this evening and continuing through the overnight hours into Monday morning.

As the rains become more widespread throughout the day and into early Monday morning, we anticipate rain intensity to remain mostly light to moderate with hourly rates, generally below an inch per hour as instability remains very limited across the area. There is however still the possibility that some of the embedded cells could include thunderstorms particularly overnight into monday morning, which would then enhance locally heavier rain rates, which could reach upwards to the 1 to 2 inch per hour range. It's these cells that we would need to continue to concentrate on for any possible isolated flooding, especially if they enter our urban corridors or begin training over the same areas that saw heavier rains from last night. WPC continues to highlight a level 1 to 2 risk for flooding across the vast majority of our region for today and into Monday. However, the vast majority of the rain, continues to remain of the beneficial variety across our region. WPC highlights a level 1 of 4 risk for flooding across parts of the Coastal plains for Monday.

As for amounts, hi-res models continue suggesting widespread totals in the 1 to 4 inch range with some isolated pockets of up to 6 inches not out of the question for areas that see repeated rounds of rainfall. However, almost everyone should see at least a half inch to an inch when all is said and done. These totals may seem like a lot but we arent expecting any heavier torrential downpours but rather some good old fashioned steady cool rain that will occur over a period of several days rather than all at once.

Regarding temperatures, as expected, today is certainly a cloudy rainy, gloomy day. For the rest of this afternoon highs should remain stifled in the upper 50s to mid 60s. Monday looks to be more of the same with yet another dreary and raw day across our forecast area. Lows however wont drop off too much as the clouds should keep most of the area fairly insulated with most staying in the upper 40s to mid 50s.

LONG TERM

(Tuesday through next Sunday) Issued at 1258 PM CST Sun Nov 8 2026

Our main upper level low eventually exits to the northeast by Tuesday however guidance continues to keep lingering shortwave energy behind the system into Tuesday night. With the continued presence of some coastal troughing to the south we will keep in some low end pops (20-30%) across the area, favoring along and east of the I-35 corridor. Wednesday into Thursday a longwave trough then becomes established stretching from the Ohio Valley into the Mississippi valley. Eventually this energy will advance southeastward from the Central plains into East Texas/Texarkana region on the western periphery of aforementioned troughing. This should help advance a weak cold front across our region at some point either Wednesday or Wednesday night. The northwest flow that occurs behind this front will bring in some drier air and finally push any lingering rain chances over our eastern areas more to the southeast and out of our area by Wednesday night.

Regarding high temps, Tuesday we should see highs rebound slightly back into the low 70s for those that see breaks in the clouds and some more sunshine. However, by Wednesday we begin to return to more normal values for this time of year with everyone getting into the low to mid 70s. By Thursday a potential front begins to move through, thus we should see highs drop back a couple of degrees into the low 70s with this trend continuing through Friday and into the weekend. Lows will trend slightly cooler with many seeing mid 50s midweek before several areas taste there first 40s of the season to begin the the first half of the weekend. Lows Sunday should be slightly warmer with most seeing the return of low to mid 50s.

AVIATION

(18Z TAFS) Issued at 1047 AM CST Sun Nov 8 2026

Most of the higher resolution model runs are sticking to a general trend for minimal late afternoon and early evening rain activity followed by an evening uptick in activity out west and spreading back east over the I-35 Corridor late tonight into Monday morning. TAFs will follow loosely along that timeline with better midday to early evening CIGs getting to MVFR and conditions dropping back to IFR as the rain activity increases again.
