THIS MORNING JUST AHEAD OF MORE LATITUDINAL TROUGH MOVING SEWD OVER
THE NRN PLATEAU.  MOISTURE PLUME FROM TROPICAL STORM PAUL IS EVIDENT
THROUGH WATER VAPOR IMAGERY STRETCHING FROM THE LOCATION OF TROPICAL
STORM PAUL OVER THE SRN TIP OF THE BAJA PENINSULA NEWD INTO THE SRN
PLAINS. 

MID/UPPER LEVEL TROUGH MOVING SEWD THRU THE NRN PLATEAU IS EXPECTED
TO INTENSIFY TODAY AS IT MOVES INTO THE 4-CORNERS AREA EJECTING
WEAKER TROUGH JUST AHEAD OF IT INTO THE CENTRAL PLAINS. 
CONSIDERABLE CLOUD COVER OVER THE PLAINS SHOULD CONTINUE MUCH OF THE
DAY LIMITING POTENTIAL INSTABILITY AND SEVERE STORM POTENTIAL.

OF THE PERIOD AS LOW LEVEL WINDS OF 40-50 KT EXTEND FROM THE CENTRAL
PARTS OF THE TX GULF COAST INTO S CENTRAL MO.  THIS IS WHEN
THUNDERSTORM ACTIVITY IS EXPECTED TO INCREASE ACROSS THE PLAINS AS
VERTICAL SHEAR INCREASES TONIGHT.  AGAIN CONSIDERABLE CLOUDINESS IS
EXPECTED TO INHIBIT POTENTIAL INSTABILITY AND SEVERE WEATHER
POTENTIAL DURING THE PERIOD.
