If temperatures plummet immediately below freezing when the rain changes to snow, then wet paved surfaces will instantly become a sheet of ice. I am still very concerned about a FLASH FREEZE. Today’s computer models have sped up the storm just a tad, but that “tad” means that the changeover from rain to accumulating snow will occur between 7:00 p.m. Rain possibly mixed with some wet snowflakes will develop Thursday afternoon, with steadier rain Thursday evening. In fact, the low will deepen so fast that it will likely qualify to be called one of those bomb cyclones that you hear about occasionally…but usually associated with those east coast Nor’easters. By dawn Thursday, the low will be in the southeast Colorado/northeast New Mexico area, intensifying rapidly as it tracks northeastward. When that happens, and especially with an intense core of jet stream wind at its base, strong low-pressure systems are generated, which will cause the storm that we’ll deal with. This less common orientation is called a “negatively tilted trough” (if you were watching Local 4 News early Monday morning, I explained this with graphics). The big dip in the jet stream (called a trough) will be oriented from northwest-to-southeast, which is less common than the more typical northeast-to-southwest oriented troughs that cross the country. This will plunge the jet stream southward, which opens the flood gates for arctic air to dive through the Plains. The intense core of jet stream wind that I wrote about yesterday - an astounding 170 mph - has now crossed the Pacific Northwest, and will dive southeast into the central U.S. Those who do get stranded on the side of the road could be stranded for a long time. But the potential for true blizzard conditions is very real, and trust me on this, you don’t want to be stranded in those conditions. I’ll tell you what I’m telling the family and close friends who have been personally asking me about people traveling to or from here on Friday: NOBODY SHOULD TRAVEL IN AND OUT OF THIS AREA ON FRIDAY.Ĭould there be a part of the day where things aren’t quite as bad as other parts of the day? Sure, that could happen. Let me be clear about this: I am not hyping this storm, and I am not withholding any information. People sometimes ask me what the “real” story is … as if I’m holding back information for some reason. Some of the severest winter conditions that we have experienced in a long time will hit the area just before Christmas, causing very dangerous travel conditions, not to mention possible power outages (some will be without heat as bitter cold arctic air streams in). The bottom line is that there is no chance that this storm will miss us. Tuesday will feature mostly rain with highs near 40 degrees.4Warn Weather – So many of you read and found useful my article on Tuesday that, for simplicity, I will keep the same format with updated information. We will make that a point of interest as we get closer. Morning lows will be near freezing, and afternoon highs will be in the low 40s.Ī little trouble moves in early Tuesday in the form of freezing rain or ice. We’ll have a few more clouds moving in on Monday, which is President’s Day. It will be another breezy day, with winds moving S at 10-20 mph, so it won’t be perfect. We’ll start with a chilly morning in the single digits to low teens, but sunshine will try to bring afternoon temps into the upper 30s to near 40 degrees. Sunday will be the best day of the weekend. Highs will hang in the low 20s all afternoon. The winds will relax a bit Saturday afternoon with a few flurries and only partly sunny skies at best. Temps will starting in the low-to-mid teens early, with sub zero wind chills. A weak disturbance will pass through, bringing scattered snow showers that may coincide with a few snow squalls. We will have a blustery Friday night and Saturday morning.
