So far, every day in July has recorded rain at Reagan National and so far highs have stayed in the 80s as a result.  However, today will finally see a change, like it or not.  Temperatures will be the big story this afternoon. Highs in the low 90s, but feels like temperatures reaching the mid to upper 90s with high humidity.  We should also keep it dry today.  But, a cold front is approaching from the Great Lakes, bringing increased clouds tonight and a chance of a few showers by dawn.  Chance of rain increases Wednesday afternoon and evening with widespread showers and thunderstorms expected. Computer models have been trending drier late this week and weekend.  A big dome of heat will gradually build in the southeastern U.S.  How far north can it build is the question.  Models are putting us in the hotter, more humid sector now as opposed to the wetter 80s solution.  Right now we'll split the difference with near 90 and a small chance of storms this weekend.  We'll fine tune the details as it gets closer, but it's looking pretty good overall.  Have a great day!
