A Pattern Change Will Bring Much Milder Temperatures by Late Next Week

A northeast wind off of Lake Michigan has spread some flurries as far west as nothwestern and north central Illinois. There will be a few flurries overnight that may linger into Sunday morning. Clouds will gradually break up on Sunday as a ridge of Canadian high pressure  shifts eastward from the plains.  It will be cold on Sunday night as the ridge edges into the area with lows near 6 above.  It will be sunny and cold on Monday with a high in the low 20's.  A very significant warming trend will begin midweek as a big pattern change takes place. Temperatures will be back up to 30 degrees by Wednesday. As a strong air flow develops out of the south,  the warmer air riding over the snow will create a lot of fog beginning on Wedesday night and lasting through Friday night.  There may be some freezing rain mixed with snow with the first preciptiation on Wednesday night.  It will be warm enough for light rain on Thursday and Friday.  There might even be some thunderstorms late in the week as a strong system moves into the area. Temperatures on Friday and Saturday may top out in the middle 40's.

  1. I love the interactive radar map! I can even zoom in on my home town in Massachusetts getting socked in with snow! Better them than us. Meanwhile 45 here on Friday. Ours will be gone. Thanks!
