VALID 12Z SAT OCT 14 2023 - 12Z MON OCT 16 2023
...A LOW PRESSURE SYSTEM WILL BRING UNSETTLED WEATHER FROM THE
UPPER MIDWEST TO THE MID-ATLANTIC REGION TODAY...
...WINDY BUT SLOWLY IMPROVING WEATHER EXPECTED ACROSS MUCH OF THE
EASTERN U.S. ON SUNDAY INTO MONDAY AS THE STRONG LOW PRESSURE
SYSTEM MOVES OFF THE EAST COAST...
...DRY ACROSS MUCH OF THE WESTERN HALF OF THE COUNTRY BUT RAINY
ALONG COASTAL PACIFIC NORTHWEST AND NORTHERN CALIFORNIA...
A LOW PRESSURE SYSTEM CURRENTLY CENTERED OVER THE MIDWEST WILL BE
THE MAIN WEATHER MAKER ACROSS THE COUNTRY OVER THE WEEKEND. THIS
SYSTEM IS FORECAST TO SLIDE EASTWARD THROUGH THE OHIO VALLEY TODAY
BEFORE REACHING THE MID-ATLANTIC STATES THIS EVENING. BANDS OF
MODERATE RAIN, WITH LOCALLY HEAVY RAIN AND SOME EMBEDDED
THUNDERSTORMS, CAN BE EXPECTED ACROSS THE MIDWEST AND LOWER GREAT
LAKES EARLY THIS MORNING BUT THEY WILL QUICKLY SPREAD EAST INTO
THE MID-ATLANTIC REGION TODAY. BY SUNDAY, THE LOW IS FORECAST TO
MOVE OFF THE MID-ATLANTIC COAST AS IT MERGES WITH ANOTHER LOW
PRESSURE WAVE MOVING UP THE COAST OF THE SOUTHEASTERN U.S., THE
MERGER WILL RESULT IN A LARGER AND MORE POTENT SYSTEM TO RAPIDLY
MOVE OFF THE EAST COAST SUNDAY MORNING. THE HEAVY RAIN ASSOCIATED
WITH THE SYSTEM IS NOT EXPECTED TO IMPACT LAND DUE TO ITS RAPID
MOTION BUT THE ASSOCIATED STRONG WINDS ARE EXPECTED TO AFFECT MUCH
OF THE EASTERN U.S. ON SUNDAY, WHICH WILL ONLY SUBSIDE SLOWLY BY
SUNDAY NIGHT INTO MONDAY. CLOUDS AND SOME RAIN WILL LINGER
FARTHER INLAND OVER THE LOWER GREAT LAKES AND OHIO VALLEY WITH DRY
CONDITIONS ACROSS THE DEEP SOUTH.
MEANWHILE, MAINLY DRY CONDITIONS WILL PREVAIL ACROSS MUCH OF THE
WESTERN HALF OF THE COUNTRY FOR THE NEXT COUPLE OF DAYS. THE
EXCEPTION WILL BE ALONG COASTAL PACIFIC NORTHWEST AND NORTHERN
CALIFORNIA WHERE RAINY CONDITIONS WILL LIKELY CONTINUE AS A
WEAKENING FRONT BECOMES NEARLY STATIONARY JUST OFFSHORE. CALM
WIND AND CLEAR SKIES WILL RESULT IN BELOW FREEZING TEMPERATURES
OVER THE CENTRAL TO SOUTHERN HIGH PLAINS AS WELL AS NEARBY ROCKIES
IN THE EARLY MORNING HOURS FOR THE NEXT FEW DAYS, PROMPTING FREEZE
WARNINGS/WATCHES TO BE ISSUED FOR THIS REGION.
