Monday Afternoon Update: 5:20 p.m.

The temperatures topped the 100-degree mark today, making this the hottest day of 2008. At last report, the airport was reporting 102, with a heat index of 102. In weather like this, the best advice is to take it extra easy a stay well hydrated. Tonight it’s still going to be rather warm, with hazy conditions. Lows will be near 70-degrees. Tomorrow is going to be another very hot day, with highs near 100. This means that the heat index will again be topping the 100 degree mark and you will certainly want to try tackling those outdoor actives early. In fact, by 11:00 a.m. tomorrow morning we should be reaching the low 90s. A few isolated thunderstorms are on radar today and a stray shower or storm can’t be ruled out for tomorrow. The good news is that temperatures won’t be as brutal for the mid-week timeframe.

By Wednesday and Thursday a boundary will drop in from the north and help to lower temperatures by a few degrees. We will have a more clouds and a better chance for a passing shower or thunderstorm in the afternoon hours. This boundary will washout over the region, with slightly drier conditions by Saturday. Another weak boundary will help to promote a better coverage of afternoon thunderstorms again on Sunday and Monday of next week. This will be our only hope for increasing the chance for rain this week.

Right now Tropical Storm Dolly is expected to track towards the Brownsville, TX area. By that time, the system may be a category one hurricane at landfall. The landfall timeframe is forecasted to happen Wednesday morning. Right now Hurricane Watches are up for Port O’ Conner south, across the Mexican border. After landfall, a ridge should force Dolly westward. Also, Cristobal is a strong tropical storm now gradually shifting northeast away from the U.S. East Coast.
