SAN ANTONIO — Here we go again. A heat advisory will be in effect from noon through 8:00 pm Monday for Bexar and surrounding counties. Temperatures will fall into the upper 70s and low 80s tonight then soar into the upper 90s and triple digits Monday afternoon. No rain, near record temps, and sunshine are expected Monday. Heat index values from 108°-112° likely. San Antonio will get caught under the heat dome again early in the week as high pressure slides east over Texas. The only rain we have in the forecast is Wednesday and that’s a 10% over eastern counties.

Tonight: Mostly clear and warm. Wind: SE 5-10 mph. Low: 79°.
Monday: Very hot and mostly sunny. Heat index of 108°. Wind: SE 5-10 mph. High: 100°.

Tropics

Tropical Storm Warnings and Watches are in effect for the Lesser Antilles. Tropical Storm Dorian has strengthened a bit with max sustained winds of 50 mph. A small storm in size but worth monitoring as it moves toward the Caribbean. Dorian will produce 2” -4” of rain with higher amounts of 6” over the Lesser Antilles. Tropical-Storm-Force Wind should arrive over Barbados Monday early afternoon (just after 12pm). Still too soon to pinpoint specific impacts to Puerto Rico, Dominican Republic, and Haiti. As of today, Dorian is forecast to near category 1 hurricane strength late Tuesday into early Wednesday before approaching Puerto Rico. No significant changes to forecast track since yesterday.
