...REMARKABLY QUIESCENT PATTERN CONTINUES ACROSS MUCH OF THE
CONTINENTAL UNITED STATES....
...LIGHT RAIN SHOWERS ACROSS UPPER MIDWEST/UPPER GREAT LAKES
TODAY...
...SNOW/RAIN SHOWERS CROSSING OREGON, IDAHO TOWARD
YELLOWSTONE/TETONS...
...WELL ABOVE-AVERAGE TEMPERATURES CONTINUE OVER THE CENTRAL AND
EASTERN U.S...
A PROGRESSIVE MID-LEVEL TROF WILL CONTINUE TO RAPIDLY ADVANCE
ACROSS SOUTHERN CANADA AND CLIP THE NORTHERN TIER STATES THROUGH
THE GREAT LAKES WEDNESDAY. THE ASSOCIATED COLD FRONT WILL BRING
SOME LIGHT RAIN SHOWERS ACROSS THESE AREAS, BUT SLOWLY DRY OUT AS
IT CROSSES SOUTHEAST CANADA AND THE NORTHEAST BY THURSDAY. WARM
AIR ALONG/AHEAD OF THE FRONT WILL ONCE AGAIN PROMOTE WELL ABOVE
NORMAL TEMPERATURES ACROSS NEW ENGLAND TODAY WITH SOME LOCALES
POTENTIALLY REACHING RECORD TODAY AND WEDNESDAY BEFORE RETURNING
TO NORMAL, OR SLIGHTLY BELOW NORMAL THE DAY AFTER THE PASSAGE.
THE MID-SECTION OF THE U.S. WILL ONCE AGAIN SEE LARGER SCALE
RIDGING ALLOWING TEMPERATURES TO RISE 15-20 DEGREES ABOVE NORMAL
INTO WEDNESDAY/THURSDAY WITH SOME LOCATIONS IN THE SOUTHERN PLAINS
PUSHING DAILY RECORDS AS WELL INTO THE LOW 90S. SO NOT DANGEROUS
HEAT, BUT CLEARLY ATYPICAL.
A WEAK UPPER-LEVEL UPPER LEVEL LOW WILL ADVANCE INTO THE PACIFIC
NORTHWEST BY WEDNESDAY INTO THURSDAY. THIS SYSTEM WILL BE BELOW
AVERAGE IN MOISTURE TRANSPORT AS IT QUICKLY MOVES THROUGH THE
TERRAIN OF OREGON, IDAHO INTO SOUTHWEST MONTANA/NORTHWEST WYOMING
PRODUCING SNOW SHOWERS AND MAYBE LIGHT RAIN TO THE LOWER
ELEVATIONS.
