WARM WEATHER TO CONTINUE THROUGH THE WEEKEND WITH MOSTLY CLOUDY MORNINGS, PARTLY CLOUDY AFTERNOONS AND A VERY SLIGHT CHANCE OF ISOLATED SHOWERS OR THUNDERSTORMS
Mostly cloudy early, becoming partly cloudy and warm this afternoon this a 10% chance of isolated showers or thundershowers. High temperatures will range from the mid-80's in Galveston to the upper-80's inland. Expect southeast winds at 10-15 mph. It will be partly cloudy and mild this evening, becoming mostly cloudy after midnight. Overnight lows will be in the mid-70's. Winds will be from the southeast at 10-15 mph. Friday should bring mostly cloudy skies early, becoming partly cloudy and warm later in the day with a 10% chance of isolated showers or thundershowers. High temperatures will range from the mid-80's in Galveston to the upper-80's inland. Expect southeast winds at 10-15 mph. Saturday should bring mostly cloudy skies early, becoming partly cloudy and warm with a 10% chance of isolated showers or thundershowers. Highs will range from the mid-80's on the Island to the upper-80's on the mainland. Look for southeast winds at 10-15 mph.
High pressure over the Gulf of Mexico, surface low pressure over New Mexico and west Texas and an upper-level high pressure ridge should combine to bring warm temperatures and persistent southeast winds to our area through the weekend. There will be very slight chance of an isolated shower or two as deep moisture at the low levels flows into southeast Texas, otherwise look for mostly dry and warm conditions. This morning’s surface weather map shows a stationary frontal boundary extending from New Mexico southeast across north central Texas. A surface trough digs south from a low over eastern New Mexico to northern Mexico with another low located just north of El Paso. High pressure continues to ridge west over the Gulf of Mexico and southeast Arkansas. Elsewhere, a cold front is pushing south from southeast South Dakota through the Great Lakes. A complicated series of lows and fronts then extends east and northeast into Canada and New England. Far to the west, a slow moving Pacific cold front is edging east from California to Montana. The upper-level map shows an upper-level low over Iowa and Wisconsin with a trough digging south into Alabama and Georgia. A high pressure ridge has developed over west Texas and the southern Rockies. Further west, a deep upper-low is located over Washington and Oregon with a trough dipping south into California. Looking ahead, warm temperatures, southeast winds and partly to mostly cloudy skies will prevail. We will see a very slight chance of rain through the weekend as deep moisture continues to flow into the area. The upper-level trough over west Texas should slowly break down by early next week, with the trough to the west moving into the center of the country. This may improve rain chances some next week, through most of the action will be off to our north.
Tropical storm development is not expected through tomorrow.
