A strong cold front will approach the region later today and the result will be numerous PM showers and thunderstorms. Some of the rain this afternoon and evening will be heavy at times and some of the storms can be on the strong-to-severe side. A few spots along the I-95 corridor could end up with a more than two inches of rainfall by tomorrow morning; especially, north of the PA/MD border. A secondary cold front is forecast to pass through our region on Wednesday night. High pressure is expected for Thursday with another warm front possible on Friday.

A stalled out frontal system just to our south will advance northward this weekend as a warm front and then a new cold front will approach the eastern seaboard on Monday from the Ohio Valley - both of these fronts will keep us quite unsettled right through Monday night. Scattered showers and thunderstorms are likely today, tomorrow, and Sunday (Father’s Day), and then more numerous showers and thunderstorms are likely on Monday and Monday night with the next cold front and some of that rain can be heavy at times. As far as temperatures are concerned, it’ll remain fairly comfortable today, but the weekend will bring about a noticeable warm up and also more humid conditions following the passage of the warm front.

The front that passed through the region yesterday has stalled out just to our south and it will turn around this weekend and head back to the north as a warm front. Given the close proximity of the frontal boundary zone, our weather will become more unsettled as we close out the work week with an increasing chance of showers and thunderstorms. The threat for rain will continue on both weekend days and the highest likelihood for showers and thunderstorms will come on Monday as a strong cold front slides into the eastern US. As far as temperatures are concerned, it’ll actually be a bit more comfortable today and tomorrow when compared to the recent heat, but the weekend will bring about a noticeable warm up following the passage of the warm front.

The passage of a back door cool front later today will bring some relief today to the DC metro region and it’ll actually become rather comfortable for Thursday and Friday with highs near the 80 degree mark on both days. This same front will stall out just south of here over the next 24 hours and then it’ll turn around and push northward as a warm front this weekend. With the front nearby, it’ll become increasingly unsettled as we go through the remainder of the work week with the chance of showers and thunderstorms and the threat for rain will continue through the weekend and into early next week.

The current heat wave will peak today with possible record-breaking temperatures in the middle 90's - but this hot spell also ends today. A back door cold front will drop through New England later today and it should then slide south of here by later tomorrow bringing noticeable relief to the region for the second half of the work week. That same front is likely to turn around and push northward as a warm front this weekend keeping us unsettled with the chance of showers and thunderstorms and its passage will bring warmer air back to the region for Saturday and Sunday. One final note, NASA postponed last night's planned sounding rocket launch at Wallops Island - the 6th postponement - and they are supposed to try again this evening between 9:04 and 9:19 PM.

A dramatic warm up will begin this weekend in the Mid-Atlantic region and continue into the middle of next week. Temperatures should reach the 80 degree mark for highs this afternoon, mid-to-upper 80’s on Saturday, and then climb past the 90 degree mark on Sunday afternoon. On Monday and Tuesday of next week, temperatures are likely to climb into the middle 90's and humidity will become quite noticeable. After that, there is likely to be a bit of a cool down for the DC metro region thanks to the passage of a back door cold front. One final note, NASA is now scheduled to launch a sounding rocket at Wallops Island, Virginia on Sunday evening between 9:04 and 9:19 PM. Look to the southeastern horizon to see colorful artifical clouds that should be generated as a way of monitoring upper-level winds.

“Astronomical" summer begins on June 21st this year and the exact date and time are determined by the Earth’s position relative to the sun. Meteorologists use the annual temperature cycle to determine the time frame for the seasons by splitting the year into four quarters with the statistically hottest three months of June, July and August considered to be “meteorological" summer. Whatever the declaration, the next several days will bring about a dramatic change in temperatures to the Mid-Atlantic region with much cooler-than-normal conditions today, tomorrow and Thursday and then a big warm up for the weekend and much of next week. This upcoming warm up is quite likely to bring the return of 90+ degree highs to the DC-to-Philly-to-NYC corridor.
