..SYNOPSIS
AN UPPER LOW WILL PROGRESS EASTWARD INTO QUEBEC, WITH A LARGE AREA
OF CYCLONIC FLOW ALOFT OVER MUCH OF THE EASTERN CONUS ON MONDAY.
WEST OF THIS TROUGH, AND UPPER RIDGE WILL REMAIN FROM THE FOUR
CORNERS STATES INTO WESTERN TX.
AT THE SURFACE, AN EXPANSIVE AREA OF HIGH PRESSURE WILL RESULT IN
RELATIVELY STABLE/DRY CONDITIONS OVER MUCH OF THE CENTRAL AND
EASTERN CONUS. THE LEADING COLD FRONT AND BULK OF ASSOCIATED
THUNDERSTORM ACTIVITY WILL STRETCH FROM THE WESTERN ATLANTIC INTO
THE NORTHERN GULF. WESTERN PORTIONS OF THE FRONT WILL EXTEND INTO
CENTRAL TX, WHERE SOUTHERLY WINDS WILL MAINTAIN A MOIST AND
MARGINALLY UNSTABLE AIR MASS.
EARLY DAY ACTIVITY MAY EXIST OVER KS INTO OK WHERE SOUTHERLY 850 MB
FLOW MAY YIELD ELEVATED INSTABILITY ATOP THE SURFACE FRONT.
ADDITIONAL STORM DEVELOPMENT IS POSSIBLE SOUTH OF ANY SUCH ACTIVITY
INTO NORTHWEST TX, BUT POOR LAPSE RATES AND SHEAR ALOFT WILL LIMIT
SEVERE POTENTIAL. OTHERWISE, SCATTERED AFTERNOON THUNDERSTORMS ARE
LIKELY OVER MUCH OF THE INTERMOUNTAIN WEST AS AREAS OF MIDLEVEL
MOISTURE PERSIST.
