Early Start For Summer Heat

Summer oficially starts at 2:06pm on Thursday (June 21) but the hazy, hot & humid summer type weather has kicked in a few days early. The high at BWI-Marshall was 94, three degress short of the record 97 set in 1957. It hit 96 at the Maryland Science Center. The heat and humidity will be around on Tuesday but the record of 99 set in looks safe. Low to mid 90s are expected.

A cold front will approach the area Tuesday night. Scattered thunderstorms are likely ahead of the front. It looks like the best rain chances will be Tuesday night and Wednesday morning. There is not a good consesus in the weather computer models on the timing of the rain. What storms do develop could border on strong to severe. The jet stream is not really positioned for a major outbreak of severe weather around the Bay but the combination of the hot & humid conditions along with the lifting mechanism of the approaching front and its’ associated atmospheric ripples may be enough to pop some severe storm cells. Hail and straighline winds would be most likely. We could use a little rain. BWI-Marshall is running .42″ short on the month and 3.10″ short on the year.
