Forecast for Sunday, March 11, 2012

We all will have to set our clocks ahead by one hour at 2:00 a.m. (meaning we will lose an hour of that precious sleep) as it is time to spring ahead. In addition, a geomagnetic storm may produce an aurora that could be visible from our area (which is rare), especially away from the lights of urbanized areas. Communication and power disruptions are always possible, but the last few have not resulted in major issues.

Fire danger will be enhanced during the next several days as a relatively dry weather pattern combines with mostly sunny, low humidity, and breezy days. We have not seen any super soakers lately and that is causing the ground to dry out on the surface layers from what was a very wet spell the last half of 2011. Unseasonably mild temperatures will likely dominate in the extended forecast. Temperatures may very well be around April and early May averages for most of the next seven days.

On Sunday, expect sunny skies and maximum temperatures around 60 degrees at Philadelphia International Airport by the end of the day. Monday should end up even milder with only an increase in cloudiness towards evening.

A weak disturbance may bring the chance for rain showers late Monday into Tuesday Morning. These will be scattered and not enough to bring relief to our fire weather concerns. Tuesday high temperatures may approach or exceed 70 degrees once the sunshine reappears. A thunderstorm or two is possible with a weak cold front on Tuesday Afternoon and Evening. Precipitation coverage will be isolated in the afternoon into the night.

Behind the front on Wednesday and Thursday, temperatures will still flirt with 70 degrees. Another front on Thursday will likely be unsuccessful in taking temperatures down, 70s may now linger into the weekend!
