Looks like this afternoon has the potential for some strong storms. As the clouds dissipate the heating of the day will only lead to more instability in the atmosphere. The models and data suggest a strong mid-level shear later in the afternoon. Storms should start later in the afternoon, ending just after dark tonight.
Potential exists for heavy rain, strong wind, and a good potential for tornadoes. Below is the wording from the National Weather Service regarding tornadoes. Those West, North and Northeast of Baltimore have the greatest risk for storms.
From the NWS:
"Forecast shear parameters from the RUC and GFS show decent tornado potential with 0-3km srh around 175 m2/s2 sweat indices approaching 400 and pressure falls around 4mb/3hr. LCLs also low with dewpoints in the 70s. All of these suggest a sig risk for tornadoes."

A look at the model data and soundings data show a good chance for storms later today. Right now it is sunny and a wonderful weather day; but, the heating of today combined with a cold front moving in will allow for the development of storms. The heating of the day will allow for the "cap" to be broken which will allow for storms to "pop up" rather quickly. The main threat for the storms will be strong wind and hail. Those North of Baltimore are more likely to see storms, yet most of MD is under this threat. I anticipate these storms beginning after 5:00pm.

The rest of the week will see temps below normal as Canadian air continues to flow down to us. There are upper level disturbances moving through for the rest of the week and so thunderstorms are possible each day. These storms will be scattered and not severe. Wednesday's storms should be primarily confined to Southern MD. Those who do experience storms will find large hail as the major threat. The rest of the week those North and West of Baltimore have a greater chance for storms.

As the cold front progresses toward our area we have a good chance for strong thunderstorms. Right now I would say the timing would place these storms in Central MD around 5:00 - 6:00. The storms will be scattered, yet those who experience these storms could see hail, strong wind and heavy rain. Those on the list around the MD/PA line have a greater chance of experiencing squall line storms in the evening. Those along the Bay are at risk for tornadoes due to the interaction of the wind off of the water and the winds from the Front. I will not be surprised to see watches/warnings issued later today.

Today's temps look to rise into the upper 80s, that combined with a somewhat unstable atmosphere could produce thunderstorms later today. Storms that do form today will not be as intense as yesterday and will be more scattered then the lines that formed yesterday. Don't be surprised if watches and warnings are issued later today. Any storms that do form will be in the early evening for our area.
