Weather Outlook for May 7, 2013

Posted: May 7, 2013

A large swath of central and northeast Pennsylvania tallied no more than a few hundredths of an inch of rain (less than 5% of normal) last week.

With mainly sunny skies from Thursday to Monday, evaporation rates have risen sharply. Temperatures have stayed with a few degrees of normal due to chilly mornings (below average) and milder afternoons (a bit above normal).

Clouds have finally arrived from a pesky disturbance that has meandered through the Southeast for several days. Showers will spread into most sections by Wednesday and should linger in the eastern half of the state on Thursday. Most places will receive between a quarter and a half inch with the least in the southwest and the most in the eastern counties where more than an inch could fall. The details of the weekend forecast are muddled, but there should be at least one opportunity for showers in most of the Commonwealth and perhaps some places might see two chances of rain.

It should be quite mild on Friday and Saturday (especially overnight with readings in the 50's and 60's), but a strong cold front will sweep through during Sunday with gusty winds and be followed by drier and very chilly conditions on Monday and Tuesday (May 13-14) and some frost is possible in the valleys of northern and central Pennsylvania.

A sudden surge of very warm weather is expected during the later part of next week sending readings well into the 80's. The warmth is likely to be short-lived as more seasonal conditions return by the weekend along with scattered showers. It may turn chilly for a couple days early the following week (May 19-21).
