Another Mild Surge to Impact the East by Midweek

After a brief shot of chilly air, the mild weather pattern will return to the East by midweek.

Between 15 and 20 degrees will separate highs expected Monday and midweek through the Northeast and mid-Atlantic.

Following the passage of today's snow squalls, temperatures by Monday will fall back to near 40 degrees in New York City and the lower 40s in Philadelphia, both of which are near seasonal average for this time of year.

Still for January, it won't feel all that bad with some sunshine expected on Monday.

A Return to Mild Weather

High pressure will anchor itself off the East Coast by Tuesday and this will send a southwesterly flow of air into the Great Lakes, mid-Atlantic, and Northeast.

This flow of air coming straight up from the Gulf will send temperatures soaring above normal from Chicago through Detroit and New York City.

Below is the list of forecasted high temperatures for selected cities Tuesday and Wednesday.

City Tues. Wed. Normal
Chicago 49 44 31
Detroit 47 49 32
New York City 53 56 39
Philadelphia 57 59 41

The mercury could even crack the 70 degree mark in cities such as Richmond and Norfolk, Va.

The mild weather will be accompanied by a few showers come Wednesday, but with a lack of deep moisture, rainfall will be rather sparse.

The mild weather will persist into the end of the week across the East; however, the potential then exists for a late week storm.

This storm would develop in the form of a wave along the tail end of a frontal boundary over the Gulf Coast. Moisture and rainfall will return to Texas, Oklahoma and the lower Mississippi Valley by Thursday and that feature could lift northward by the end of the week.

Meteorologist Alex Sosnowski explains that "The details of the nature of the storm, and most importantly its critical track, will unfold early next week."

Avalanches are caused by a number of factors. Thick layers of snow and ice of varying intensity along a mountainside are weakened by the force of gravity and changing weather conditions. At some point, this large mass of snow is released down the mountain in a form of an avalanche.
