A SPRING STORM SYSTEM MOVING INTO THE REGION WILL MAINTAIN A MOIST
SOUTHERLY FLOW INTO THE AREA TODAY. THE MOIST AIRMASS IN PLACE
WILL COMBINE WITH DESTABILIZING CONDITIONS THIS AFTERNOON FOR THE
DEVELOPMENT OF SHOWERS AND A FEW THUNDERSTORMS AND SOME OF THE

STRONG WIND GUSTS. EXPECT A PERSISTENT WIDESPREAD RAIN TO DEVELOP
LATE TONIGHT AND CONTINUE THROUGH MUCH OF FRIDAY AS THE STORMS
SYSTEM MOVES DIRECTLY OVER THE REGION. COOLER AIR WILL LOWER SNOW
LEVELS AND A CHANGE OVER TO WET SNOW IS LIKELY IN THE INCIDENT
AREA BY FRIDAY MORNING. HOENISCH
