September 16th, 2013 Forecast

Clouds will increase tonight in advance of our next cold front.  Due to the extra cloud cover, temperatures will be milder than they have been the past two nights.  A shower or sprinkle is possible late tonight as the front slides through, but don't expect any significant rainfall from this.  Lows will range from the low to mid 50s in the Lehigh Valley to around 60 in the city.

Monday will feature improving weather.  The day will start off gray with a leftover shower or sprinkle around, but by midday skies will begin to brighten and continue to do so through the afternoon.  Highs will reach the low and mid 70s across the region, perhaps warmer if the sun breaks out earlier.

High pressure will settle in for Tuesday, Wednesday, and Thursday.  Temperatures will turn a little milder each day with bright sunshine.  A cold front will approach from the west by the end of the week.  The models don't agree on the timing, but it could come through at any point during the weekend, so for now I have to put a shower and thunderstorm chance in the forecast for both Saturday and Sunday.  One of those two days will likely end up dry, but it's hard to say which one at this point.  We will keep you updated as new model data becomes available.
