Looks like for now that Thursday and Friday may be overall dry days. Humidity levels will start to creep up as there will be an approaching low pressure system with a trailing cold front. I'll have to put in a slight chance for an isolated thunderstorm on both days. Thursday's high will reach the upper 70s to near 80, and Friday will probably be one of the warmest day of the year so far for the area in the lower to middle 80s.
For Saturday and Sunday, instability levels will rise from the low pressure system and will increase the chance for more scattered thunderstorms. As of now I do not believe that each one will last a long time, but at some times I believe that rain tires will be needed. You will notice cooler temperatures as the highs are only expected to reach the middle 70s on Saturday, and the upper 60s to near 70 for Sunday. As of now, I do not believe there will be any severe weather during this time, but will let you know if that changes.
Just remember that we will have live radar up and running on our blog site, and I'll have weather updates on my Twitter feed @RaceWx4You. Have a great day.
