Cold Front to Erase Eastern Warm Spell

The sunny and warm weather across the East will be erased by a cold front which sweep through the area Monday night and Tuesday. This front will bring an end to the mild weather and give way to more seasonably cool conditions for the latter part of the week.
The good news before the cool down is that residents from Boston and New York City to Philadelphia and Washington, D.C., will be able to experience one more warm and sunny day on Monday.
Temperatures Monday afternoon will rise into the upper 60s across many cities and towns in the mid-Atlantic and New England. Highs in the 70s will be common from Richmond, Va., on southward to the Gulf Coast.

A cold front, the same one producing severe weather in the Plains, will track into the mid-Atlantic Monday night before moving to the Eastern Seaboard Tuesday.

This front will bring a round of rain and a few thunderstorms to many areas as it passes though, but the real change will come behind the front as temperatures fall 15-20 degrees from Monday's values.
Below is a table of Tuesday's high temperatures compared to Monday's high temperatures for selected cities:

City	High Mon.	High Tues.	Difference
Pittsburgh

65
43
-22


Philadelphia
67
55
-12


New York City
67
54
-13


Washington, D.C.
67
51
-16


Buffalo
63
41
-22




Note that the temperatures on Tuesday aren't actually all that cold, but are closer to normal for this time of year. The air mass coming in behind the aforementioned front is modifying as it moves eastward.
Dry weather will also take hold once again with high pressure building in behind the departing front. That will support sunshine across most locales in the East through the end of the week.
This extended dry stretch is good news for residents still trying to clean up from Hurricane Sandy and the nor'easter. It will also give power crews more time to restore electricity to areas still without.
