…Wind Chill Advisory for Northern Coastal Bend Tonight through Friday Morning…

…No Winter Precipitation is Expected…

A strong cold front will move through South Texas early this evening ushering in a very cold air mass which will persist into the weekend.  Temperatures will drop into to mid to upper 30s across most of South Texas overnight with gusty north winds and wind chill values in the 20s.  A Wind Chill Advisory has been issued for the Northern Coastal Bend for Tonight through Friday Morning, and this may need to be expanded farther south to include the entire Coastal Bend. Small craft advisory conditions are expected over all marine areas where wind gusts to gale force will be possible.  High temperatures on Friday will hold steady in the upper 30s to around 40 degrees with patchy light rain and drizzle. Atmospheric temperatures will not be cold enough for winter precipitation. Temperatures will remain chilly through the weekend with highs Saturday in the mid-upper 40s and highs Sunday in the mid to upper 50s.

South Texas Impacts:

Wind Chills: Wind chill values will range from the upper teens to lower 20s across the northern Brush Country and Victoria Crossroads area late tonight through Friday morning.  Wind Chills in the mid to upper 20s can be expected across the southern Coastal Bend and Coastal areas.  To stay warm, wear several layers of clothing, including hat, scarf and gloves.

Wind Speeds:  Strongest winds will be observed along the Coast where North winds of 20 to 30 mph with gusts 35 to 40 mph will be possible Tonight through Friday.

Marine Conditions:  North winds increasing to 25 to 30 knots after midnight Tonight and persisting through Friday. Gusts to gale force possible.  Bays will be Choppy to Rough.  Seas building to 6 to 8 feet offshore with occasional seas up to 10 feet.  Winds and seas gradually diminishing on Saturday. Small Craft Advisories are in effect for Tonight through Friday Night.

Overview: Scattered thunderstorms are expected to develop across parts of West and West Central Texas tonight and grow into a large thunderstorm complex that will move from west to east across the state. Ahead of this complex, isolated showers and thunderstorms may develop across Southeast Texas that pose a damaging wind or brief tornado threat before the main thunderstorm complex moves across the region. This complex will move quickly east, with dry and warm conditions expected across the region after 12 PM.

While the thunderstorm complex will be capable of heavy rain, the speed at which it moves across the region will minimize any flooding threat these storms pose.

Changes Since Last Briefing: Minor refinements to timing and impacted locations

Hazards: Thunderstorms capable of damaging winds, hail, and isolated tornadoes

Timing: 4 AM – Noon Monday (Travel impacts during the morning commute possible)

Location: Severe weather will be possible across most of Southeast Texas tonight into
Monday morning, with best potential at this time appearing to be north of the Highway 59 corridor.

Timing & Area of Concern:

The greatest risk for storms will be along and north of a Del Rio to Uvalde to Victoria line.

12 AM – 3 AM: Rio Grande and Western Edwards Plateau
2 AM – 5 AM: Hill Country (West of I-35)
4 AM – 8 AM: Along and East of I-35
Threats & Impacts:

Hail: Quarter sized or greater.

Winds: Isolated wind gusts up to 60 mph.

Tornadoes: An isolated tornado is possible, mainly along and east of I-35 corridor.

Rainfall: 1/4-1/2 inch with isolated amounts up to 1 inch for the eastern Hill Country, Central Texas, and areas east of I-35. Less than 1/4 inch Rio Grande, Western Hill Country, and remainder of South Texas. Due to the speed of this system no significant flash flooding is expected.

Overview:

A potent upper level disturbance and Pacific cold front will generate a quick round of showers and storms late tonight through early Monday morning. The best chances for storms will be along and north of a Del Rio to Uvalde to Victoria line. Environmental conditions are favorable for some isolated storms to produce large hail in addition to damaging wind gusts across the region. In addition, a lower threat of an isolated tornado can’t be ruled out, mainly along and east of the I-35 corridor. The Storm Prediction Center has placed much of the area under a Slight Risk for severe storms tonight, but the area with the highest potential for severe weather is in red in the attached image.

Confidence:

Moderate

A few disturbances over the next few days will provide an opportunity for some rain and even some possible strong storms come Sunday night and Monday morning. The risk for severe storms is marginal for Sunday through Monday morning with some possible hail. Then a strong cold front will look to impact the region come Wednesday morning bringing much cooler temperatures into the late week.

There is a marginal risk for severe weather on Sunday night and lasting through Monday morning as an upper level shortwave moves over the state. The primary threat will be hail up to one inch in diameter.
