A mostly mild week is ahead

November 9, 2015 0 Comments

Sunshine continues to dominate our weather picture as we start the second week of November, a month that is not typical known for sunshine. On average, the city of Rochester experiences overcast skies with little or no sun at all a whopping 53 percent of the time in November making it the cloudiest month of the calendar year on average. So far, this month hasn’t been typical at all with above normal temperatures recorded on seven of the first nine days and sunshine has reigned supreme the vast majority of the time.

As we’ve seen over the course of this entire autumn season, the jest stream is well to our north with a ridge over the eastern two-thirds of the continent, allowing some very warm air to influence our weather. Temperatures aren’t as warm as the past couple of weeks when record readings were in jeopardy, but we’re still solidly on the mild side. We’ll have high temperatures about ten to 15 degrees above normal for this time of the year.

A large storm system will move in for Wednesday and Thursday in a trough of cool low pressure in the midweek that will draw in some chilly, November-like weather.

This upcoming system will draw in some warm, unstable air from the Gulf of Mexico, setting the stage for a potential severe weather outbreak to our south. Damaging winds and tornadoes will be possible in Missouri, southern Illinois, and Arkansas. We’ll have a few rumbles of thunder by Wednesday afternoon, but severe weather locally appears less likely. Rain and strong northwest winds along and just behind the cold front with this system will make for a raw and unpleasant Thursday. A few snowflakes will even be possible by Thursday night.

Sunshine and quiet, mild weather looks to return for the weekend as the storm system moves on the east and another ridge builds northward.

An upper-level ridge of high pressure will move in for the weekend, allowing our temperatures to rebound nicely at least for a couple of days. High temperatures look to make it into the 50s for a few days in the middle part of the month. A stronger system will bring a chance for rain for late next Monday and Tuesday and, of course, more wind to the weather picture.
