Monticello, AR- After a very mild night in which the mercury had trouble falling into the lower to mid 70's, temperatures on Monday, Labor Day 2009 managed to climb again into the 90's on the back of partly to mostly sunny skies.
Although some parts of the Midsouth received an appreciable amount of precip when it did rain, many regions south of the I-30 corridor have received little or no rainfall, thanks to a "cap" situated over the Midsouth trailing back into the Arklatex area. A "cap" or "lid" is nothing more than a layer of warm air aloft, several thousand feet up, which inhibits thunderstorm development, even in the presence of very unstable air(which we do NOT have).
Even with the cap in place most of the upcoming week, and isolated thundershower still cannot be ruled out.
Later in the week a cold front will approach the Midsouth and could again increase our precipitation chances.
Until then, enjoy the vestige air of summer for a little longer!
