Alert Days for Heat and Storms Across Maryland for Friday into the weekend
Friday kicks off the string of Alert Days, with heat index values expected to exceed 105 degrees in parts of central Maryland. Actual air temperatures will climb into the mid to upper 90s, but stifling humidity will make it feel significantly hotter-especially in urban corridors like downtown Baltimore, Columbia, and Essex. The excessive heat will strain infrastructure, increase the risk of heat-related illness, and pose challenges for outdoor workers and vulnerable populations.
A few isolated thunderstorms are also expected to flare up late in the day, primarily during the late afternoon and early evening. The Storm Prediction Center has placed the Baltimore metro area under a Level 1 Marginal Risk for severe weather, meaning a few storms could produce damaging wind gusts or brief downpours. Overnight Friday into Saturday will remain warm and muggy, with lows barely dipping below 80 degrees in the city.
Storm Risk Increases Over the Weekend
Saturday will bring more of the same. Heat index values will approach 100 degrees by midday, with another round of scattered afternoon and evening storms. While not everyone will see rainfall, those who do may experience locally heavy rain and gusty winds. Given the repeated storm threat and lingering heat, Alert Days remain in effect for both Saturday and Sunday.
By Sunday, storm coverage will likely increase slightly, especially by late afternoon and evening. Highs will hover near 90 degrees, though high humidity will once again push heat index values into the upper 90s. The scattered nature of the storms means some neighborhoods could remain dry, while others deal with intense downbursts or brief flooding.
Next Week: Another Heat Surge Before Relief
Monday will bring a brief lull in storm activity, but the heat will continue. By Tuesday, temperatures are expected to spike again, reaching the mid-90s, with humidity pushing the heat index back into the 100-105 degree range. An additional First Alert Weather Day may be necessary for Tuesday due to the extreme conditions.
By Wednesday, a stronger cold front will approach the region, bringing yet another chance for strong to severe thunderstorms-potentially more widespread than earlier in the week. The front will also usher in a refreshing air mass.
Thursday will feel dramatically different. High temperatures will tumble into the low 80s, and much of the region will enjoy overnight lows in the 60s, particularly in the suburbs. Lower humidity and clearer skies will provide a much-needed break from the prolonged heat and stormy patter

Severe storms Thursday in Philadelphia region to bring heavy rain, damaging winds. Here's the forecast.
Thursday will bring the fourth day in a row with a NEXT Weather Alert, though it will be due to storms and flooding, not necessarily the heat. It will be hot, but it won't be as hot as the previous days. Those showers and storms will develop ahead of an approaching cold front that will put an end to this heat wave and usher in much cooler air by Friday. They will also be bringing flooding rain and the chance for a severe storm or two, mainly in the form of damaging winds. The Storm Prediction Center has our area in a moderate risk for flooding, which is a 3 out of 4 on the risk scale. The primary time frame for the greatest impacts will be 2 p.m. to 9 p.m., with a heavy focus near the evening commute. On Friday, the high temps will likely only top out in the mid-low 70s, which is much closer to the record for the coldest high temp (69 degrees) than the normal high in the upper 80s. Friday is also the start of August and the start of an extended cooler stretch of air bringing relief from the heat through the first week of the month. Highs Friday and into the weekend will be in the upper 70s to low 80s, with morning low temps in the mid-low 60s. In fact, many places Sunday morning will likely be in the 50s. Thursday: NEXT Weather Alert for heavy rain. High 90, Low 76. Friday: Shower early. High 73, Low 67. Saturday: Beautiful. High 82, Low 64. Sunday: Sunny, nice. High 84, Low 62. Monday: Mostly sunny. High 85, Low 62. Tuesday: Mostly sunny. High 82, Low 64. Wednesday Showers possible. High 98, Low 78. NEXT Weather Radars Hourly Forecast

High heat, flood threats in Tri-State Area trigger multiple First Alert Weather Days
The CBS News New York First Alert Weather Team has issued First Alert Weather Days through the end of the work week due to heat, storms and flood threats. Wednesday brings high levels of heat and humidity along with a storm threat, followed by a flood threat for Thursday and Friday. A heat advisory is in effect for nearly the entire area through 8 p.m. Wednesday. An excessive heat warning is in effect for northeastern New Jersey through 8 p.m. Wednesday. An air quality alert is in effect for all areas except the upper Hudson Valley through 11:59 p.m. Wednesday. Tuesday was day two of the current heatwave, and it proved to be another record breaker with some locations, including Newark and LaGuardia Airport, reaching the century mark. Tuesday night, warm and muggy conditions will persist, with lows ranging from 70-80 for the most part. Those wishing to catch a glimpse of the double meteor shower Tuesday night will be in luck. Sky conditions should be near perfect for viewing both the Alpha Capricornids and Southern Delta Aquariids across the Tri-State Area. To have two meteor showers going on at the same time is rare. Central Park may tie a record for the highest minimum temperature on Wednesday morning, as the forecasted low of 80 matches the record high low of 80. One more extremely hot day is on tap for Wednesday. Once again, highs will reach the mid to upper 90s, with heat indices in the low 100s. Most of the day will be sunny, but by the late afternoon hours, the threat of isolated severe thunderstorms returns. The greatest hazards associated with these storms would be damaging winds. These storms should diminish by sunset. Of greatest concern, however, is the threat of flooding rains that is now setting up for Thursday. While the chance of severe thunderstorms is low, forecast models are indicating that rounds of continuous heavy rain and thunderstorms will develop over the region, producing possibly between 2-4 inches of rain. Some models are suggesting that the heavy rain will linger into Friday as well.

Maryland heat wave grows worse, strong storms will end it Thursday
Our current heat wave will grow more intense Tuesday. Temperatures and humidity will be higher than on Monday. We'll have another brutal day of heat and humidity Wednesday before the extreme heat departs the area Thursday with heavy thunderstorms. Monday marked day number four of Maryland's current heat wave. High temperatures rose into the middle 90s with abundant sunshine. High temperatures only get hotter Tuesday into Wednesday. Alert Days are in effect Tuesday through Wednesday due to the dangerous combination of heat and humidity. Heat index temperatures will soar well over 100° as early as mid to late morning and the heat index will remain above 100° through at least the dinner hour. Actual temperatures will soar into the mid and upper 90s. Some highly urbanized areas, like Baltimore City, could see high temperatures approach the century mark. The Orioles are playing a doubleheader Tuesday. Both games look extremely hot, but the first game will be the toughest to endure with blazing sunshine and temperatures in the middle to upper 90s. Please wear light weight, light colored clothing along with a hat and sunglasses. Hydrate frequently during the game and take breaks from direct sunshine. First pitch temperature for game 1 will be around 93° with temperatures in the 90s for the entire game. Feels like temperatures will be over 100° for the entire game. The second game at 6:35 p.m. also looks hot and steamy. First pitch temperature is forecast to be 93°. At least for the second game, the sun won't be as much of a factor. Even with a night sky, temperatures stay close to 90° for most of the innings. The good news for both games is that thunderstorms won't be an issue, so no rain delays or postponements will occur. A slow-moving cold front will approach us late Wednesday into Wednesday night. Thunderstorm coverage looks rather isolated Wednesday evening, but the storms that do manage to form could be severe. The main impacts would be drenching downpours, intense lightning, and localized damaging winds. Most neighborhoods across central and eastern Maryland will stay dry Wednesday evening and night. An additional wave of low pressure will develop along the cold front Thursday into Friday. The timing of the cold front is now trending toward the afternoon and evening hours. This would allow for heat and humidity to build Thursday morning and midday ahead of the developing storms. This means the threat for pockets of damaging winds and flash flooding is increasing due to the available heat and humidity for storms to thrive. There could be a few broken lines of strong to severe storms Thursday, especially 3 p.m. through 11 p.m. The WJZ First Alert Weather Team is monitoring Thursday for the potential of a First Alert Weather Day for severe weather and/or heavy rainfall. If new computer model information remains consistent on timing and intensity of Thursday's storms, a First Alert Weather Day will be issued for Thursday soon. This same cold front will continue to inch southward on Friday, so showers linger throughout a good chunk of the day. With the cold front being to our south, major heat relief will be felt with high temperatures only reaching the middle to upper 70s. At this time, the weather this weekend looks simply outstanding! High pressure will be arriving from the northwest. This will help draw down some refreshing air from Canada Friday night through the weekend. In addition to the comfortable temperatures, we'll enjoy dry weather with partly to mostly sunny skies. Afternoon high temperatures Saturday and Sunday will only reach the lower 80s, and overnight lows will be great for open window weather, dipping down into the 50s and 60s. If this forecast trend holds for the upcoming weekend, this could be one of the nicest weather weekends of the summer across
