AREAS AFFECTED...PARTS OF CENTRAL INTO EASTERN NORTH DAKOTA
CONCERNING...SEVERE THUNDERSTORM WATCH 409...
VALID 280455Z - 280700Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 409
CONTINUES.
SUMMARY...TRENDS WILL CONTINUE TO BE MONITORED, BUT A NEW SEVERE
WEATHER WATCH PROBABLY WILL NOT BE NEEDED TO THE EAST OF SEVERE
WEATHER WATCH 409.
DISCUSSION...TWO-HOURLY SURFACE PRESSURE RISES ON THE ORDER OF 2-6
MB WERE STILL EVIDENT WITHIN THE EASTWARD PROPAGATING COLD POOLS
OVERSPREADING CENTRAL NORTH DAKOTA IN THE 04Z SURFACE OBSERVATIONS.
HOWEVER, FURTHER COOLING AND SOME DRYING OF THE BOUNDARY-LAYER HAS
BEEN EVIDENT IN OBSERVATIONS ACROSS EASTERN NORTH DAKOTA, WHERE
SOUTHERLY FLOW AROUND 850 MB IS ALSO FORECAST TO GRADUALLY WEAKEN
OVERNIGHT AHEAD OF THE REMNANT CONVECTIVE SYSTEM. LESS UNSTABLE AND
WEAKENING UPDRAFT INFLOW SEEM LIKELY TO CONTRIBUTE TO SUFFICIENT
FURTHER WEAKENING OF STORMS THAT A NEW SEVERE WEATHER WATCH MAY NOT
BE NEEDED TO THE EAST OF THE CURRENT WATCH.
