Our 'heat wave' type pattern will continue today under high pressure aloft, but will gradually weaken as we go through the upcoming week. Sunday's official high (CGI) was 96, making it the hottest day of the year thus far...and today is not likely to be much different. Heat Advisories remain in effect for most of the region....with H.I. numbers back in the 100 to 105 range by mid-afternoon. A few isolated thunderstorms will likely pop up....models are inconsistent on where this might happen so no attempt to fine-tune.
As we go thru the week the upper ridge will be breaking down gradually, which should allow for a slow decrease in daytime temps and a slow increase in rain chances. Could even be some stronger storms again by about Wed/Thur/Friday. However right now not seeing any clear frontal passage, so we likely will stay with warm, humid conditions....just not as hot and with more clouds/showers. By next week we'll be drying out and warming up once again. So far June is running about 5 degrees above average...making it one of the warmest June months since 1952.
