MOSTLY CLOUDY EARLY WITH A CHANCE OF SHOWERS OR THUNDERSTORMS, BECOMING PARTLY CLOUDY AND WARM THIS AFTERNOON WITH A SLIGHT CHANCE OF THUNDERSHOWERS
PARTLY CLOUDY AND WARM TOMORROW AND FRIDAY
Mostly cloudy early with a 40% chance of showers and thunderstorms, becoming partly cloudy and warm this afternoon this a 20% chance of thundershowers. High temperatures will be in the mid-80's. 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 low-70's. Winds will be from the southeast at 10-15 mph. Thursday should bring mostly cloudy skies early, becoming partly cloudy and warm later in the day. High temperatures will range from the low-80's in Galveston to the upper-80's inland. Expect southeast winds at 5-10 mph. Friday should bring mostly cloudy skies early, becoming partly cloudy and warm. Highs will range from the low-80's on the Island to the upper-80's on the mainland. Look for southeast winds at 5-10 mph.
Shower and thunderstorms continue over Liberty and Chambers counties this morning. There is a slight chance they could build back into the Galveston area as a weak cold front sags into southeast Texas. Otherwise, mostly to partly cloudy skies should prevail through tomorrow. This morning’s surface weather map shows a slow moving cold front extending from New Mexico southeast across south central Texas and then back northeast to a low over east Texas. The front then continues north-northeast to Missouri and Illinois. Another frontal boundary is northwest and north of that front, extending from Iowa east across the upper-Great Lakes to New England and the Atlantic. High pressure is located over western Kansas and north central Texas. Also, high pressure is evident over the Mid-South and far to the west over northern Arizona. A Pacific cold front is tracking east from western Canada to southern California. The upper-level map shows a high pressure ridge along the East Coast, a low pressure trough dipping south through the Plains into north Texas and a deep upper-low over Washington and Oregon. Looking ahead, warm temperatures, southeast winds and partly to mostly cloudy skies will prevail. We will see a chance of rain today as the cold front slowly sags southeast, though it should stall northwest of Galveston. High pressure aloft will build over the western Gulf and east Texas through the weekend keeping partly cloudy skies and warm temperatures around into early next week. With the high pressure in control, rain chances will be very low through the weekend and into next week. A low pressure trough will gradually develop to our west by the middle of next week and may help to set off a few showers towards the later half of the week. In other words, expect typical late May weather for our area.
Tropical storm development is not expected through tomorrow.
