Synopsis...
The cold front has passed, and the steady westerly flow has built in. Sub-freezing conditions will persist through the weekend under generally cloudy skies. A clipper system looks to move through the southwest regions on Friday.
Short Term/Long Term...
A strong westerly flow will remain through Friday, which will aid in containing temperatures in the upper 20s/low 30s as shown by MOS. WRF does show a dry pocket of air moving in for Friday, so this may allow for a few breaks in the clouds that we have seen recently. A clipper system will move in later in the day Saturday According to the WRF and MOS POPS, most areas in the southeast quadrant of the state may see a dusting to an inch of snow. This should be a relatively short lived event as it will quickly get absorbed by a strengthening low pressure system off the Atlantic seaboard. That system will be far enough off the coast for there to not be any snow, but it will allow for lake-effect snow to persist during the later part of the weekend. Once this forming Nor'easter moves into Canada, it will stimulate a southerly flow and allow temperatures to warm up about 3-5 degrees (for highs). Overall, it's going to be cold and cloudy through the end of this forecasting period.
