Winter's Wet End

The last full day of winter is going to be wet. A low pressure system is moving up through Pennsylvania today as it heads toward the Canadian Maritimes. Steady rain and fog are expected to continue over the city through noon. The warm front that projects off the low should arrive early this afternoon. Once it does the steady rain will turn showery. Showers will last until a cold front sweeps through tomorrow morning. Late tonight some of those showers could be in the form of a thunderstorm. An excellent way to herald the vernal equinox at 1:48 a.m. EDT!

Temperatures should rise throughout the day today and well into the evening hours, eventually topping out in the mid-50s. There won't be much cooling until the cold front arrives around daybreak. The low pressure system is strengthening as it moves northeastward. This will oddly mean that winds from the storm will intensify even as the storm gets further away. A strong southerly breeze will pick up during the day today, only to be replaced by a stronger westerly wind tomorrow morning.

Skies should clear tomorrow following the cold front's passage. Don't be fooled by forecasts saying the high will be in the 50s. That warmth will be long gone by the time you wake up. Tomorrow is going to be brisk, with temperatures holding to the mid-40s. The high pressure system that arrives tomorrow will stick around for a few days. No precipitation is expected over the weekend, but temperatures are expected to run slightly below normal.
