Forecast for Monday, April 16, 2012
A very warm day is on tap for Monday with record highs within reach. The record high for Philadelphia is 90 degrees. Most areas outside of the higher terrain will rise into the middle and upper eighties. Some isolated 90 degree readings are possible in typically warmer locations. At the shore, temperatures near the oceanfront will be stuck in the middle seventies.
A weak cold front will approach the region very late Monday Night into early Tuesday Morning. Instability should wane quite bit with the loss of daytime heating. The moisture also appears limited with this boundary. However, an isolated thunderstorm cannot be ruled out with the greatest chances in the western fringes of our area. There is a threat for severe thunderstorms in Western Pennsylvania tomorrow and we will watch these storms as they progress over the Appalachian Mountains for any surprises.
For Tuesday and Wednesday, the cold front will stall nearby and give us intervals of clouds. There could be an isolated shower or sprinkles, but the chance is slight at the moment. It may turn unsettled at the end of the week with a series of fronts and associated disturbances.
Until the end of the week...fire danger will remain elevated to extreme in many portions of our area.
