Mostly sunny Sunday with an isolated shower or storm in the Philadelphia region. Here's the forecast.
There was a lot of lightning associated with the storms across Maryland, so we'll be watching for perhaps one or two of those making their way closer to Delaware.
Sunday will give us mixed skies with a trend for much more sunshine than Saturday.
With the instability in the air, we cannot rule out an additional shower or rumble, especially in the late afternoon. Severe weather is likely to stay mainly north and east of the region, but we'll keep an eye on it.
Monday through Wednesday, much drier, cooler and more pleasant conditions arrive behind the cold front.
Skies will be sunny, humidity will be low, and highs will only reach the low to mid-80s. These may be some of the nicest days so far this summer.
By Thursday, we warm to the 90s again, and on Friday, another chance of storms is in the forecast.
Sunday: Shower, storm. High 91, Low 74.
Monday: Much nicer. High 87, Low 71.
Tuesday: Sunny and dry. High 83, Low 65.
Wednesday: Sunny skies. High 86, Low 65.
Thursday: More humid. High 91, Low 67.
Friday: Partly cloudy. High 95, Low 73.

Tough heat wave to develop across Maryland, storm chances increase
Our next heat wave of summer should begin today across much of Maryland. This will be the first 90-degree day of many through the middle of next week. The toughest stretch of this heat and humidity will come Friday through Tuesday with Friday and Tuesday obtaining the highest feels like temperatures. A major pattern change toward cooler and more comfortable weather will take place the second half of next week. So hang in there during this brutal heat wave, there is major relief that will be arriving by this time next week. Today's high temperatures will reach the lower 90s with heat index values topping out in the middle 90s. Humidity levels will continue to climb this afternoon into this evening. Despite the heat and humidity, the good news there won't be any thunderstorms to disrupt outdoor work or activities. Overnight lows tonight will not be as refreshing with temperatures only dipping down into the middle 70s. The WJZ First Alert Weather Team has issued First Alert Weather Days Friday, Saturday, and Sunday for the one-two punch of intense heat and possible afternoon and evening severe storms. Friday will be one of the toughest days of this upcoming heat wave. High temperatures are forecast to reach the upper 90s to near 100°. Tropical levels of humidity will make the heat feel even worse and possibly dangerous. Feels like temperatures will easily surpass 100° with some isolated locations reaching nearly 110°. The weekend will feature more brutal heat and tropical humidity. While weekend temperatures may not be as high as Friday with additional clouds and thunderstorms, the combination of higher humidity will offset temperatures being slightly cooler in the lower to middle 90s. This heat wave will continue right into the middle of next week with another round of dangerous heat likely Tuesday as highs climb into the middle to upper 90s with feels like temperatures reaching 105° or higher. The WJZ First Alert Weather Team has tagged Tuesday as a possible First Alert Weather Day for this brief round of potentially dangerous heat. Next Wednesday will be another hot and steamy day, but scattered strong thunderstorms that arrive later in the day should officially break this heat wave. Strong to severe thunderstorms will begin to form in this incredibly hot and muggy airmass starting Friday afternoon. The coverage of strong to severe storms will grow each day through Sunday. The storm threat should briefly end by Monday and Tuesday of next week. Friday afternoon and evening storm coverage should be isolated. More places than not will stay dry, but the best chance for a few powerful storms will be across northern and northeastern Maryland. The timeline would be after 3 p.m. through 11 p.m. Any storm could have intense cloud to ground lightning, blinding downpours, and pockets of damaging winds. As a weak boundary stalls across the area this weekend, additional thunderstorms will develop Saturday and Sunday afternoon and evening. During the weekend, the entire state is game for the possibility of strong to severe storms. Storms will produce copious amounts of clouds to ground lightning along with torrential downpours given the high tropical humidity levels and intense heat. Storm coverage on Saturday will be isolated to widely scattered. Numerous afternoon and evening strong thunderstorms are possible Sunday afternoon and evening. The jet stream position will favor a major pattern change for our area starting Thursday of next week and continuing through next weekend. The large and expansive heat dome will be pushed to our south and southwest allowing cooler air from Canada to put an end to the heat and humidity for at least several days. While it will be cooler late next week into next weekend, disturbances will spark off scattered showers and storms from time to time. Luckily none of the days look like washouts.

Drier air moves in after round of scattered showers across South Florida
Scattered showers and storms will move across South Florida on Thursday before drier air moves in just in time for the weekend. The chance of rain will be highest in the morning through the midday hours, with the potential for some heavy downpours and localized flooding. The atmosphere remains juicy and unstable due to an upper-level area of low pressure which has led to all the wet weather over the last few days. Afternoon highs will climb to the low 90s, but when the humidity is factored in, it will feel like the upper 90s and 100s. There is a moderate risk of rip currents along the Atlantic beaches and the UV index is extreme. There are no alerts or advisories for boaters over the Atlantic or Keys waters. Late Thursday afternoon, a plume of Saharan dust will begin to move and storms will push inland and to the west. The drier air and high pressure will bring drier, hotter conditions on Friday and through the weekend. It will be a scorcher due to the lack of rain and cloud coverage. Highs will soar to the low 90s and it will feel like the triple-digits. The National Weather Service may issue heat advisories. Early to middle of next week the chance of rain rises with the potential for passing showers and a few storms. The National Hurricane Center is monitoring a trough of low pressure over the north-central Gulf that has a low potential (10% chance) of development as it moves generally westward across the north-central portion of the Gulf. Regardless of development, this system is expected to bring heavy rain and the potential for flooding along the Gulf coast.

Hot and humid weather is back today. Did you miss it? It's going to be around for a while with highs near 90° through at least Tuesday of next week. So if you want to impress friends and neighbors, here's a handy tip. WEATHER LINKS: Current Conditions | School Closings & Delays | Submit Your Weather Photos You can get a big tip on just how humid things are going to be by just looking at morning lows.

The other big story is a return of downpours and the risk of flash flooding that is coming our way, and arriving on Friday. Not everyone is going to see big rain totals, but those who do will have a chance for flash flooding. Any storms during the afternoon will bring frequent lightning and some gusty winds. Our severe weather chances right now look marginal at best, but can't be ruled out. When it comes to the forecast, highs today should hit the low 90s in most places. Rain chances should be enough to keep highs in the mid to upper 80s on Friday, Saturday, and Sunday, with morning lows in the mid to low 70s due to how humid it will be. Rain chances on each of those days will be isolated to scattered with downpours possible. Monday rain chances look to be in the isolated range, with scattered rain chances back on Tuesday and Wednesday. Temperatures will return to be near or just below average the rest of next week.
