Mercury reaches 90s again at BWI
The temperature at BWI-Marshall airport topped 90 degrees again on Monday, reaching 91 degrees during the afternoon.
UPDATE: The official high Monday at BWI was 92 degrees. Earlier post resumes below.
It was 93 degrees at The Sun's weather station at Calvert and Centre streets downtown. Temperatures also reached the 90s at Hagerstown, Martin Airport, Washington Reagan National Airport and Dulles Airport in Virginia.
The high was not close to the record for the date - 96 degrees set back in 1991.
Monday was the fifth day of 90-degree weather for Baltimore so far this year. We hit 90 degrees at BWI on April 6 and 7. The high on May 26 was 91 degrees, and we went one degree higher - 92 - the following day.
The average daytime high temperature for Baltimore on May 31 is 79 degrees. It climbs to 86 degrees by the end of June, and tops out at 88 degrees in the third week of July.
May 2010 ends with an average temperature of about 67 degrees, which is more than 4 degrees above the long-term average for the month, and the warmest May since 2004, which averaged 69.8 degrees at BWI. The high for the month was 92 degrees, on the 27th. The low was 35
degrees, on the 10th. Hardly seems possible now. It's also worth noting - again - that the last of the December and February snow piles finally melted at BWI during the first week of May.
Cooling degree days in May - a measure of the demand for energy for cooling - were running more than twice the norm for the month. Watch for that on your next electric bill. I know my AC is cranking.
The month of May in Baltimore is also ending with about 3.5 inches of rain - about a quarter-inch below the long-term average.

Monday doesn't look too bad at this distance, but it will be hot, with a forecast high near 90 derees.

"The April 2010 map of temperature anomalies shows that for the first four months of the year anomalous warm temperatures were present over much of the world, with the exception of cooler-than-average conditions across the higher-latitude southern oceans, the northern Pacific Ocean, along the western South American coast, Mongolia, northern China, northern Australia, the south central and southeastern U.S., northern Mexico, and most of Europe and Russia.

The atmospheric setup for the next three or four days is kind of complex and unusual. There is a big high-pressure system off the coast that's sending cool, moist Atlantic air our way today on east winds. It has also pushed a cold front south as far as eastern North Carolina, keeping us cool and damp and drizzly into the morning.
pressure moves across the Great Lakes to our north. Before that front gets here, though, we'll see winds shift to the south and southwest, bringing warmer, wetter air our way. That will mean some morning showers, a break, and then more showers and thunderstorms possible late in the afternoon or Friday evening.

Our Lancaster bureau chief, Charlie Charnigo, reports from his FRiday lunch spot that the towering snow pile he has been watching since the February storms has finally melted away. Says he:
When the statisticians out at Sterling looked at just the daily high temperatures, they found that the average daily high of 69.7 degrees last month was the 6th-warmest on record for the city, tying for that spot with April 1976.
