WINTER STORM WARNINGS AND ADVISORIES ARE OUT FOR A WINTER STORM
THAT IS CURRENTLY DUMPING SNOW IN COLORADO. THE STORM IS A RESULT
OF A CLOSED LOW SITUATED OVER THE OKLAHOMA AND KANSAS BORDER.
HEAVY RAIN IS ALSO FALLING ALONG THE STATIONARY FRONT...WHICH
STRETCHES FROM THIS LOW CENTER TO THE NEW ENGLAND COAST...AND
AHEAD OF A COLD FRONT PUSHING THROUGH WEST TEXAS. THIS FRONTAL
SYSTEM WILL PROGRESS EASTWARD AS A JET OF STRONG UPPER LEVEL
ENERGY MOVES IN BEHIND THIS CENTRAL LOW. MOISTURE FROM THE GULF
WILL FEED THIS SYSTEM...MAKING FLOODING CONDITIONS ALONG THE
FRONTS POSSIBLE.
THE WARM AND SUNNY CONDITIONS ALONG THE EAST COAST WILL SOON BE
COMING TO AN END. THE DOME OF HIGH PRESSURE WILL BE PUSHED OFF THE
ATLANTIC SHORE AHEAD OF THE FRONTAL SYSTEM ON FRIDAY. THOSE IN THE
MID-ATLANTIC HOPING TO TAKE IN THE NEAR PEAK FALL FOLIAGE WILL
HAVE DREARY VIEWING CONDITIONS THIS WEEKEND AS THE HEAVY RAIN
ENTERS THE REGION.
THE STORM SYSTEM PUSHING ONSHORE IN THE PACIFIC NORTHWEST IS
BRINGING ANOTHER ROUND OF RAIN TO THE AREA. LIGHT TO MODERATE RAIN
WILL FALL IN THE NORTHWESTERN U.S. STATES THROUGH EARLY TOMORROW
MORNING. THIS WILL BE FOLLOWED BY A BRIEF REPRIEVE ON THURSDAY
EVENING...BEFORE ANOTHER UPPER LEVEL DISTURBANCE BRINGS MORE
RAIN...AND SOME SNOW TO THE HIGHER TERRAIN.
