Troy’s Audio Weather Webcast for Thursday / 19 April 2018….

 

Updated 915am CT – Thursday / 19 April 2018

… Rain / Thunderstorm Chances Friday Night into Saturday …
… Cold Front Passes Saturday Night …
… Sunshine Returns for Sunday into the New Week …

On the Weather Map…

On the surface map… a cold front extends from the southeastern USA to southern Louisiana to just off the Texas coast then onshore again over south Texas then into northern Mexico. High pressure, to the north of the front, is centered over the central plains states. As a result of this surface weather pattern, our surface winds are north northeasterly.

On the upper air map… a series of upper level low pressure disturbances is embedded in a rather zonal (west-to-east) wind flow over the USA. The first disturbance is over the northeastern USA with another stronger one over Nevada and California. As a result of the upper air weather pattern, the 30,000 foot winds over our local area are westerly 50 to 55 mph.

What I am Seeing As I Look Ahead…

The front, which moved through the area in the midday hours yesterday, is moving off the Texas coast this morning.

Our next upper level low pressure disturbance and associated stronger cold front is still expected to approach the area beginning tomorrow night and will move through the area by Saturday night. I expect rain shower and thunderstorm activity beginning Friday night with chances peaking Saturday into Saturday afternoon as the system moves eastward. The latest NWS/Storm Prediction Center guidance has reduced the severe weather risk for Saturday to “marginal” so I will continue the possibility for a few stronger thunderstorms locally, with a possible hail and stronger straight line thunderstorm wind threat, for Saturday into Saturday afternoon with the chance of thunderstorms decreasing by evening. Based on the information above, the NWS/Weather Prediction Center guidance has pulled back on the forecast rainfall amounts.. now suggesting rainfall of 1/4 inch locally.

Once the cold front passes later Saturday night with reduced rain chances, skies will clear with plenty of sunshine and less humid conditions for Sunday into the first half of next week.

Have a good Thursday..
