Three weather stories in the next three days: Warm, Snow, Cold. First the warm air surges north for everyone generally east of Iowa. Records will be shattered! Also severe weather will be a serious threat south of Milwaukee. Then cold air crashes in and changes rain to snow, heavy snow in fact. Very hard to pin down the timing of the cold air and where the rain will be when that happens, but the snow map should give you a good idea. And finally, cold air dives south from Canada and brings us back to where we were last week. Dangerous wind chills will be prevalent.
A crazy weather week is in front of us. Snow...warmth...snow....cold. First, Snow will erupt in the Dakotas and Northern Minnesota tonight and pile up quickly, with up to 7" or 8" in some spots. Then tomorrow a strong warm front will push north and will shatter record highs in many places! Severe weather is also possible, in IL, WI, IN, IA, MO. Then, an arctic cold front will crash in and change rain over to heavy snow. The timing and location of saturation will really impact snow totals. (look for a map tomorrow). Then Thursday, will bring dangerous wind chills! Here, we, go!
A relatively weak winter storm, will bring major impacts to the Midwest Sunday and Sunday night. The worst part of the system will be the major icing. The worst accumulating ice looks to take place in Iowa, with up to a third of an inch. This will bring tree branches down an take out power for thousands. The hope is that the areas that see freezing rain will switch over to all rain and lessen the blow. On the far northern extent snow will fall, but nothing too serious. Be sure to check local advisories on this system. Forecasts will change, as a tenth of a degree will affect icing!
It has been the largest arctic cold outbreak in two years. Some snow is headed for the Midwest late in the week. A northern piece of energy will emerge from the Rockies and phase with a southern storm system. Depending on how quickly the phase together will have a major impact on the amount of snow. Right now the consensus in computer models would put down a general 1-3" with areas up to 4", and lake enhanced areas over 6". Another system will move in for Sunday, this one looks a little stronger and will be watched carefully.
Haven't posted in awhile, it has been pretty quite. Tonight and tomorrow will bring some light snow for many areas, see map. Another system will bring the chance for some snow showers, especially in northern areas. Next, attention turns to early next week. The coldest air on the year will dive south, leading to highs below zero, cold enough to close schools. The outbreak looks to stick around until Wednesday, when a warm front will move through and cause winds to shift in a southerly direction. This will lead to a likely storm on Thursday, will rain and accumulating snow. Stay tuned.
One storm will bring rain and fog to areas in the midwest, it will also bring a considerable snow to the Dakotas will some areas seeing up to 10" to maybe a foot. Then on Saturday night an artic front will pass through the area and slow down. At this time a storm system will ride up and drop some snow in the cold sector. After Sunday it looks like the coldest air of the season will be on the front door. It looks to be even cold late week and into the next week. Stay tuned.
Thursday will bring a massive snow melt to all of the midwest. A storm system will move north from Mexico, bringing ample moisture along with it. Many areas will see a half inch or more. Once the rain is done fog will develop in many areas still with some snowpack. With warm air, a saturated atmosphere, and light winds, the fog will likely be dense in areas. Meanwhile, NW parts of North Dakota will see a few inches of snow by the weekend, with the potential of more this weekend. Areas in Minnesota should also watch for snow for the weekend, stay tuned for that.
It is looking more and more likely that late this week will be a tale of two storms, weatherwise. Before the storm move in a January thaw will occur with temperatures soaring into the 30s and 40s, with highs 10-20 degrees above normal for the whole midwest. Then, the first storm will move in ahead of an arctic front. It appears the storm will be quick enough to avoid the cold air and drop mainly rain in the Midwest, with heavy rain to the south. This will even more some weaken the snow pack in areas to the north.
Then only a couple days later attention will turn to the next possible system. One problem is models do not always do a good job when there are two storms within a few days, so uncertainty is low. However, a area a of heavy snow is possible from MN to WI to IA. The timing would be Saturday into Sunday. We will keep an eye on this system as it bears watching. A lot to work out of the next few days, stay tuned!
A weak clipper-like system will move through parts of the Midwest tonight. It will have nearly no moisture to work with, except from the lakes. However it may spawn a few snow showers that could coat roadways in Minnesota and Wisconsin, but nothing much over a half inch. There will be several hours where wind will be favorable for some lake effect snow in parts of Michigan (see map). Nothing major that these areas are not use too, but as always use caution on the roads, even if its only a few inches.
