STRONG HIGH PRESSURE OVER EASTERN CANADA. AT THE UPPER LEVELS, THERE
IS RIDGING OVER THE CENTER OF THE COUNTRY AND UPPER LEVEL LOWS OFF
BOTH COASTS OF THE US. OVERALL, THE PATTERN WON'T CHANGE MUCH TODAY
OR WEDNESDAY. LATEST 00Z SOUNDING SHOWS A LOT OF MID AND UPPER LEVEL
DRY AIR AND FORECAST SOUNDINGS SHOW THE DRY AIR ALOFT REMAINING IN
PLACE. THERE WILL BE ENOUGH LOW LEVEL MOISTURE IN PLACE WITH THE
STEADY N/NE BREEZE FOR WIDELY SCATTERED SHOWERS TO CONTINUE ACROSS
THE EAST COAST METRO, WITH OVERALL FAIRLY DRY CONDITIONS OVER THE

AS WE HEAD TOWARDS THE END OF THE WORK WEEK, HEIGHTS CONTINUE TO
FALL ACROSS THE REGION AND EVENTUALLY AN UPPER LEVEL LOW WILL FORM
IN THE VICINITY OF CUBA OVER THE WEEKEND. WRAP AROUND MOISTURE WILL
INCREASE RAIN CHANCES, ESPECIALLY ACROSS THE EAST COAST METRO. IN
ADDITION TO THE HIGHER RAIN CHANCES, THE PRESSURE GRADIENT WILL
TIGHTEN ONCE AGAIN AS STRONG HIGH PRESSURE BUILDS INTO NEW ENGLAND.
EXPECT BREEZY NE WINDS THIS WEEKEND INTO EARLY NEXT WEEK, WITH EARLY
INDICATIONS OF WIND GUSTS OF 30-40 MPH POSSIBLE, ESPECIALLY ALONG
THE COAST.
HIGH TEMPERATURES DURING THE EXTENDED PERIOD WILL BE FAIRLY
CONSISTENT, RANGING FROM THE LOW TO MIDDLE 80S EACH DAY. OVERNIGHT
