10/29 Technical Discussion

Synopsis:

The forecast period appears to be a quiet one, with a very little chance of precipitation today. After that, the main story will be the temperatures returning to seasonable values as compared with the past week. Things don't get really interesting until the end of the next work week, when the GFS shows the potential for an interesting storm.

Short-term:

Mostly sunny skies look to be the rule for our forecast period, except for today with clouds and the possibility of showers due to the last of the low pressure system that has been in the area for a few days. Models have shifted the clipper system mentioned by the previous forecasting shift even further north, meaning that we forecasted only the chance of cloudiness on Sunday for the Commonwealth as a whole and no precipitation.

Long-term:

Winds from the north will keep our temperatures low on Monday. The latest GFS run has moved the coastal low that could have affected us early next week further up the coast. We are not even anticipating significant cloud cover from that system. Our next weathermaker looks to be a system that would dive down from Canada toward the end of next week. Models are currently showing the 540 line for that potential system as far south as the Carolinas. Could this storm be our first chance for frozen precipitation?
