Weather Watch


Even with the major storm that moved right across our region on Saturday, we got less than two-thirds of an inch of rain at most locations in Otsego County, and for the first three weeks of November, total precipitation for the month has been only around one inch.

That’s only about 40 percent of the normal precipitation.

Once again, the past week showed the very reliable correlation between a ``reverse temperature anomaly’’ and dry weather in Otsego County.

After a very mild start to November, since Sunday temperatures averaged well below normal, with a strong northwest flow and the jet stream diving southeastward from central Canada to northern Florida.

With this kind of pattern, Montana is west of the jet stream and misses all the cold air, the southeastern states stays unusually cold for so early in the season.

In our area, the cold, dry weather pattern will continue right through at least early next week.

On Friday the Alberta clipper that raced southeastward, will redevelop off the New England coast, and reinforce the very cold air, with variable cloudiness, a northwesterly wind, a few snow showers, and highs only around 30 degrees.

On Saturday, high pressure will build eastward from the Great Lakes and Ohio Valley and drier air will take over with partly to mostly sunny skies and highs in the mid-30’s. A westerly flow of cold, dry air will prevail on Sunday, with partly sunny skies and highs from 35 to 40 degrees.

A storm system will move north of the Great Lakes on Monday and a southwesterly flow ahead of the low, will bring milder air; look for partly sunny skies and highs in the low 40’s.

We may get a few snow showers as a weak cold front moves through the area on Monday night, then partly sunny skies and highs from 35 to 40 degrees on Tuesday.
