FORECAST:

Upper level low will give us unsettled weather for today in a Southwest flow aloft. The high and low will be pushing each other around, more precipitation expected South of our area, depends on how much push the low has. Flurries likely sometime tonight, the brunt of the snow will come early Thursday morning. Warmer temperatures for today and Thursday but back to  Northwesterly flow aloft with the Arctic front bringing cool clear conditions on Friday. The high will be the dominant pattern for at least another week. Guesstimates: 1-3 cm by Thursday morning, 2-6 cm by Friday morning.
