HAZARDOUS WEATHER OUTLOOK NATIONAL WEATHER SERVICE JACKSON MS 259 PM CST MON MAR 7 2011
AN EPISODE OF NUMEROUS THUNDERSTORMS PRODUCING HEAVY RAINFALL AND POSSIBLY SOME SEVERE WEATHER IS EXPECTED TUESDAY NIGHT INTO WEDNESDAY. HAIL TO THE SIZE OF QUARTERS...DAMAGING WINDS TO 60 MPH...AND POSSIBLY A FEW TORNADOES...CAN BE EXPECTED WITH THE MOST INTENSE STORMS. A POTENT DISTURBANCE IN THE JET STREAM WILL COMBINE WITH VERY MOIST AND UNSTABLE AIR MOVING NORTH OUT OF THE GULF OF MEXICO TO RESULT IN THUNDERSTORM DEVELOPMENT TUESDAY NIGHT. A CONTINUED INFLUX OF MOIST AND UNSTABLE AIR FROM THE GULF THROUGH THE NIGHT IS EXPECTED TO FEED MULTIPLE ROUNDS OF STRONG TO POTENTIALLY SEVERE STORMS. IN ADDITION...THESE STORMS WILL LIKELY PRODUCE RAINFALL RATES OF 1 TO 2 INCHES PER HOUR...AND MULTIPLE STORMS MOVING ACROSS THE SAME AREA COULD PRODUCE LOCALIZED RAINFALL TOTALS OF SEVERAL INCHES IN A PERIOD OF 12 HOURS OR LESS. THIS COULD RESULT IN FLASH FLOODING...ESPECIALLY OVER AREAS ALONG AND SOUTHEAST OF THE NATCHEZ TRACE PARKWAY. THE COVERAGE AND INTENSITY OF STORMS SHOULD DIMINISH BY MIDDAY WEDNESDAY.
