Overnight rain, storm chance expected as next cold front arrives
Isolated strong-to-severe storm or two possible between 1am and 4am Wednesday
BRYAN, Texas (KBTX) - The next cold front to reach the Brazos Valley comes in a window between 12am (north) and 5am (south) Wednesday. After a day of gusty winds increasing the moisture and humidity, a quick chance for rain to a few rumbles of thunder will be possible on the leading edge of that cooler air.
WEDNESDAY 1AM UPDATE
While non-severe, strong storms continue to slowly move through parts of the Brazos Valley early this morning. PinPoint Radar estimates wind gusts 40mph+ possible just ahead of the heaviest rain. Reports of high wind, thunder, and heavy rain came out of Robertson County and the Franklin area as storms passed through during the 12am hour.
Scattered rain is attempting to come back together across Milam County to reach those in Burleson and Brazos Counties -- including Bryan / College Station. Stronger portions of this line are anticipated to push high wind across Milam and Houston Counties over the next hour.
TUESDAY 11:30PM UPDATE
The National Weather Service has issued a SIGNIFICANT WEATHER ADVISORY for Milam and Leon Counties until 12:30am. As strong storms move into the area at 45mph, wind gusts up to 40mph are possible in a few portions of the line.
Noisy thunderstorms are expected to reach the Hwy 79 corridor over the course of the next hour.
TUESDAY 11PM UPDATE
A thin line of strong thunderstorms is moving closer to the Brazos Valley tonight. As of the hour, SIGNIFICANT WEATHER ADVISORIES have been issued just north of Milam, Robertson, and Leon Counties for the potential of brief wind gusts 40-50mph. Those advisories currently expire at midnight.
This line of storms is only 10 to 15 miles wide, but is producing short bursts of heavy rain to the tune of 1″ to 3″ per hour. Upstream from the Brazos Valley, PinPoint Radar estimates a quick 0.75″ to 1.25″ of rain fell as this line of storms moved toward the I-35 corridor.
Current time of arrival remains the same locally. Midnight - 1am across the northern tier of the Brazos Valley, 1am - 2am for Bryan-College Station, and continuing south reaching the South and Southeastern Brazos Valley by 4am.
TUESDAY 1PM UPDATE
While the overall odds for a strong-to-severe thunderstorm is low, the chance cannot be ruled out. That especially holds true for those across the Northern and Northeastern Brazos Valley between midnight and 4am. The Storm Prediction Center has placed that tier of the Brazos Valley under a MARGINAL (1 out of 5 - noted in green below) Risk for severe weather through this time period.
Should a storm manage to draw concern, gusty wind in excess of 40-50mph+ would likely be the most inclement outcome. That said, a brief tornado or small hail threat cannot be ruled out. These are anticipated to be the exception rather than the rule.
As for rainfall, most of the Brazos Valley will wake to find a few drops to a few hundredths of an inch of rain in the gauge Wednesday morning. Those under stronger storms could collect a localized quarter to half-inch of rain.
