Cloudy skies will be the rule for the next 4 or 5 days. Temperatures will slowly turn cooler and the chance of rain will steadily increase. This will be due to the approach of a strong cold front and it’s attending upper level jet stream disturbance. These features with then interact with Hurricane Sandy. That’s the big picture for the next several days.
The finer details and timing will become clearer as we get into the weekend and discover whether the computer models have it right…or are even closer to being right. If they are…Sandy and the hybrid system it will become…may indeed be a storm deserving of superlative titles and nicknames. We have never seen an October hurricane make land fall on the U.S. east coast, let alone a hybrid Hurricane/Nor’easter hit this area. If this system delivers what computers simulate, effects will be just what the National Weather Service described in their latest hazardous weather outlook:
MAJOR FLOODING. UPWARDS OF 5 TO 10 INCHES OF RAINFALL MAY AFFECT
CENTRAL MARYLAND...WASHINGTON DC...AND NORTHERN VIRGINIA.
DAMAGING WINDS. IN CONCERT WITH THE HEAVY RAIN WINDS OF TROPICAL
STORM FORCE COULD CAUSE THE DOWNING OF MANY TREES AND POWER LINES.
COASTAL FLOODING. PROLONGED EASTERLY FLOW AND A FULL MOON ARE
EXPECTED TO PRODUCE MINOR COASTAL FLOODING THIS WEEKEND. MORE
SIGNIFICANT COASTAL FLOODING IS POSSIBLE ON THE WESTERN SHORE OF
THE CHESAPEAKE BAY AND TIDAL POTOMAC RIVER EARLY IN THE WEEK.
SMALL CRAFT ADVISORIES WILL LIKELY BE NEEDED THIS WEEKEND. DEPENDING
ON THE TRACK OF SANDY...TROPICAL STORM FORCE WINDS ARE POSSIBLE
OVER THE WATERS SUNDAY NIGHT THROUGH TUESDAY.
