May 7 – We will remain in this cooler than average temperature pattern for at least the next week. The core of the cold air will settle in tonight and Monday after one last impulse of rain.  So there are two weather elements to focus on: 1) Rain showers today; 2) Frost potential Monday and Tuesday morning.

Simulated Radar:

Note- This model is exaggerated. The rain should not be this solid intense. But I wanted to show the areas where showers are possible. This includes near and north of Baltimore this morning and mid day. Then southern Maryland may have a band of showers late afternoon and evening.

Cool Afternoon:

A typical May 7 would b ring a high of 71ºF to Baltimore. Today will be about 10 degrees below average.

Chilly Monday Morning:

The record low for Baltimore on. May 8  is 33ºF in 1997. We may have a chance to get the record on May 9 (36ºF set in 1966)


Frost Potential:

To get frost, temperatures do not have to hit freezing. The air temperature is measured at 5 to 6 Feet above the ground. But the ground can reach 32ºF while it is warmer just above.  The best chance will be in the areas I highlighted in purple… farther north and west of I-95 and the Chesapeake Bay. Check out the late frost and freeze map and data for our region.
