Mostly Sunny, Afternoon Storms

…HEAT ADVISORY REMAINS IN EFFECT FROM 11 AM THIS MORNING TO 9 PM EDT THIS EVENING…

Current Surface Map
A cold front remains to our north while high pressure over the southeast continues to keep the region in hot, humid air. Showers and thunderstorms are expected to develop this afternoon with some of the storms possibly becoming severe with damaging wind and large hail. Highs today will again be near 100 degrees, with heat index values topping 105.

The cold front will slowly move southward, continuing rain chances tonight and tomorrow but more importantly it will drop temperatures about 10 degrees. Highs tomorrow will be around 90. Additionally, showers and thunderstorms are likely again tomorrow as the front remains in the area.

Two More Days of Heat

Current Surface Map
High pressure over the southern Appalachians will continue to push warmer air into the region today and tomorrow.

Temperatures are expected to approach 100 degrees this afternoon under mostly sunny skies. Although it will be hot, dew points are expected to drop into the 60s which will keep heat index values down.

The humidity will return tomorrow as a cold front approaches from the northwest. Expect scattered showers and thunderstorms to develop possibly becoming severe and producing locally heavy rainfall. Highs will be in the mid 90s.

Here Comes the Heat Again

Current Surface Map
Another mini heat wave is coming to the region for the first half of this week. Hazy, hot and humid conditions are expected through Wednesday.

Today will be partly sunny with a slight chance of an isolated shower or thunderstorm this afternoon. Highs will be in the mid 90s.

Expect more sunshine on Tuesday and as a result, warmer temperatures. Highs will be in the upper 90s to near 100.

A cold front will approach on Wednesday, increasing thunderstorm chances during the afternoon and evening as temperatures again push into the mid to upper 90s. Some of the storms may be strong to severe.

One more hot day

…HEAT ADVISORY REMAINS IN EFFECT UNTIL 10 PM EDT THIS EVENING…

Current Surface Map
Today will be the last oppressively hot day for a while, as temperatures will once again approach 100 degrees. Combined with the humidity, heat index values will be near 105 this afternoon. A Heat Advisory is in effect until 10pm tonight.

There is a slight chance of showers and thunderstorms this afternoon in the higher terrain and that activity will weaken and move east, bringing a slight chance of rain into central Maryland overnight.

Tomorrow will still be warm, with temperatures in the mid 90s and thunderstorms likely in the afternoon. Some of the storms could be severe, with gusty winds and large hail.

Severe weather day

Current Surface Map
Today is the first day of Meteorological Summer and to mark the occasion, it looks like we will be dealing with a rather widespread severe weather event.

A warm front is currently working it’s way through the state, allowing moisture and warmer temperatures to stream northward. This feature, combined with a cold front approaching from the west will provide the forcing necessary for shower and thunderstorm development.

At this time, it appears enough instability and lift will be present for some of these storms to become severe and produce damaging winds, large hail, torrential rain and possibly tornadoes.

Scattered showers and thunderstorms possible again this afternoon

Current Surface Map
An upper level disturbance will move through the area today, followed by a cold front tonight. These features will touch off showers and thunderstorms as it moves through, especially east of the mountains. Expect today’s storms to be organized and affect more areas than in the past few days. Any storms that do form will be capable of becoming severe with large hail and damaging winds as the primary threats.

Be sure to stay alert for any watches and warnings that may be issued this afternoon. High temperatures today will resemble the past few days as well. Cooler along and east of the bay where highs in the mid 70s are expected, rising into the 80s further west.

Scattered showers and storms this afternoon and evening

Current Surface Map
Warm and humid air continues to build into the region, setting the stage and allowing for scattered showers and thunderstorms to develop this afternoon. Skies are expected to clear this afternoon, allowing temperatures to warm to near 80 and enhancing the instability in the atmosphere.

It appears that there will be enough instability for some of these storms to become severe, with damaging winds and hail.

SPC Day 1 Outlook
Here is an excerpt from the Storm Prediction Center:

Scattered showers and storms this afternoon

Current Surface Map
An area of low pressure moving through the Great Lakes will drag a cold front through the state this evening. Ahead of the front, strong southwesterly winds will send temperatures into the 70s and set the stage for scattered showers and thunderstorms.

There is a slight risk that these storms could become severe with large hail and damaging winds as the primary concern. Be sure to check the radar and be aware of any possible watches and warnings that may be issued this afternoon.

The showers and storms will be pushed eastward and off the coast by later this evening as the cold front moves through.
