Winter Weather Advisory

Monday, October 31, 2011

Mild Tuesday then cooling down sigificantly Wednesday with widespread rain and drizzle and poss ending as snow flurries? Dring out Thurs/Fri.

 Regional weather view.

A mild and dry Tuesday will take place region wide. Highs will be above what is expected for this time of year. Then Wednesday, a low pressure system and cold front in what appears to be the 1st system in what may lead to a more active pattern produce some widespread rains across much of the region. It will also be significantly cooler, and Enough cool air may mix in behind the system to produce some snow flurries behind the front, there would be no accumulation. Thursday and Friday things clear out and and it becomes seasonable during the day and chilly at night.


Local and Metro View. Locally we will have a fairly nice Tuesday, even though there will be some clouds we should have a fair amount of sunshine, and even without any sun we would still have nice temperatures. Highs should manage the mid 60s, with lows in the lower to mid 40s. Wednesday the low pressure and cold front will effect the area, temps will be Significantly Cooler! Highs will only be in the low to mid 40s, which we have not seen for highs yet this season. Rain has a chance of developing sometime in the morning, and will become widespread, we will probably see steady light rain or drizzle much of the day, and with the clouds and cool temps it will feel very chilly. This system has a better chance we've had in awhile to see any real rainfall amounts. Some areas may end out with near 4 tenths or more. Behind the front air may become cool enough that some of the rain may change to light snow flurries on Wednesday evening or night, but it would come to late for any accumulation, plus the ground is warm enough that any snow that would accumulate would likely melt fairly fast. Thursday and Friday things clear out and we should see good amounts of sunshine both days, we will have pleasantly chilly days, but quite cold mornings probably leading to some morning frosts. Highs will be in the mid 40s outside to Rochester Metro to the upper 40s in Rochester. 40s both days with lows in the mid to upper 20s or around 30.

Tuesday, Nice! Partly sunny to partly cloudy skies with highs in the middle 60s. Tuesday Night, Increasing clouds with lows in the low 40s. Rain showers developing towards morning

Wednesday, Significantly Cooler! Cloudy and rainy with widespread light rain or drizzle much of the day. Possible mixing with a few snow flurries in the evening. Highs in the low to mid 40s. Wednesday Night, A few showers or flurries possible, otherwise cloudy with lows in the lower 30s.

Thursday, Clearing skies and warmer. Highs in the mid 40s. Thursday Night, Chilly, Widespread frosts with lows in the middle 20s outside Rochester to the upper 20s in the city.

Friday, Sunny skies, pleasant, highs in the upper 40s. Friday Night, Not as cool, Partly cloudy with lows in the upper 30s

Looking Ahead
Forecasting models still show our weekend storm system ahead, but our area remains on the warm side of things, meaning we may actually see not just rain, but a chance of thunderstorms, especially early on Sunday, some could be strong, the storms tail end cold front sweeps through later Sunday which could lead to a few flurries. A different story will take place in Northwestern Minnesota and North Dakota which may end out getting some fairly good snow totals. By Monday the area is left with very cold but clear conditions. with slow warming towards Tuesday the 8th when a system passes just to our south. It dries out Wednesday and Thursday the 9th and 10th, Before a system and cold front sweeps very cold air down for the Friday the 11th, The air appears cool enough for maybe a all snow event for the area with that weak system which could lead to small amounts of snow. A clipper system coming down as all snow is right on its heels Saturday the 12th. Then it dries out with a very brief push of warm air arrives the 13th and 14th, before another strong cold front passes through bring more snow minor snow chances. It remains cold and the end of the run. Please stay tuned as the weeks are ahead, as the models continue to show more and more chances of snow.
