Synopsis…
The deep upper-level low is finally moving away from our region today, taking with it the dreary conditions that have plagued PA for the past several days. It will be breezy for the rest of today as the low pulls away, but we can expect a much more pleasant stretch of weather over the next few days.
Short Term…
The upper-level storm finally got caught up in a steering current and is no longer cut off from the flow. Good thing because people were starting to complain…It was a good week to travel far away though. Other than some northwesterly breezes, not much more to worry about from this system. The NW flow will continue to dominate, keeping temps from rising too much Friday and Saturday. Sunny skies will be the only story through the weekend.
Long Term…
A backdoor cold front enters the picture on Friday night as it tries to sag into the state for Saturday. Models all agree on very dry atmos conditions, so we do not see any chance of precip. Clouds and a slight wind shift will be the only effects. Things start to get more interesting starting Monday as some warmer air tries to sneak in ahead of a relatively weak cold front. Monday looks like the warmest day of this forecasting period. The 12z GFS run tries to set off a few sprinkles across NRN PA by 12z Monday, but we decided to keep all areas dry until after sunset. CMC model keeps front very weak and doesn't even have precip reach far south of I-80. GFS has light rain across most of the state, with only sprinkles reaching the Mason-Dixon Line. We went with a chc of sct or iso shwrs late Monday night for the state…possibly a little earlier in ERI and PIT. Don't see any reason it will be significant rainfall as of now.
