Winter has returned to some of our northern stations today, due to an intense low pressure system moving off the East Coast.  Strong northerly winds will impact stations in the Northeast, and BUF, ROC, and PIT will receive wet, heavy snow into Tuesday morning with the potential for moderate snow accumulations. 

After Tuesday morning, the Northeast should dry out more.  The central part of the nation is expected to see showers and thunderstorms on and off throughout the week and next weekend.  Another system coming on shore in the West will bring a lot of rain from SEA down into the desert Southwest starting Wednesday, with clearing just in time for the weekend.

Here are this week’s weather highlights:

  • Periods of light to moderate snow falling in BUF, ROC, and PIT Monday with reduced visibilities at times due to the strong and gusty northerly winds.  BUF and ROC could see a moderate amount of snow accumulation, while PIT could see one-to-two inches of accumulation, mostly on grassy surfaces.
  • Two strong, low pressure systems are creating very gusty winds in the Great Lakes (NW gusting to 35 knots), Northeast (W gusting to30 knots), and Southeast (N gusting to 30 knots) today.  Scattered showers and the gusty winds are expected to linger in the Northeast into Tuesday morning.
  • A strong system out west is expected to bring showers and even scattered thunderstorms to parts of the Pacific Northwest, California, and the Southwest.  Scattered thunderstorms are very possible for LAS, PHX, TUS, and SLC Wednesday night through Thursday, with afternoon thunderstorms possible around DEN on Thursday.
  • As the system in the West begins to push eastward, it looks to gain strength and moisture, bringing with it periods of showers and thunderstorms for the central part of the country starting Wednesday and lasting into next weekend.  A low pressure trough is also expected to bring scattered thunderstorms to parts of the Ohio Valley, and scattered showers  with some embedded thunderstorms to the Great  Lakes, including the MDW area. 
Enjoy the week!
