SummaryThe cold winds should finally begin to die down tonight as the deep trough in the jet stream begins to flatten out and surface high pressure builds more into the region. However, we may still avoid a hard freeze since winds will not go completely calm since the center of the high will be located well to our south over the Middle Atlantic states. Interestingly, because of this, the Ohio Valley, including places such as Tennessee, of all places, where the average high temperature for this date is still 70 degrees, will likely get their first hard freeze before us.

It appears that the previously mentioned Alberta Clipper will track a little farther north than expected and will likely only impact us with some cloudiness over the weekend. Temperatures will remain slightly below normal, averaging in the upper portion of the 40s during the day both Saturday and Sunday.

A deep trough in the jet stream will dive south over the northern Rocky Mountains early next week, giving them a pretty good early season snowstorm on Monday and Tuesday. This trough, and its associated surface low pressure system, will likely get cut-off for a time over the Great Plains. As a result, surface high pressure will build over us from Monday into Wednesday, keeping us dry with seasonable temperatures. The low will likely eventually get picked up by the jet stream and brought our way. The timing is a little uncertain, as it usually is once these storms get “cut-off”, but it looks like it will be late in the week before we see any effects from this storm.
