There's a lot of chatter on Twitter about a snowstorm next week. It's way too early to discuss this so be careful when you see images forecasting large amounts of snow. Here are the images posted on Twitter:
Here is what the National Weather Service is saying:
.Long Term...(Friday through Wednesday) Issued at 312 PM EST Wed Dec 1 2021 Mild Weather Continues this Weekend.... Westerly WAA over the short term will help build a broad ridge over the southern CONUS, keeping the polar jet north of central Indiana. This will allow for a warmer than normal temperatures to continue through the weekend. Friday will be 10-15 degrees warmer than average as a weak wave within the low level flow will back surface winds to the SW, advecting even warmer air into the region. Some mid level clouds will be possible on Friday given the passage of the wave, but surface moisture return will be insufficient for any low level clouds or precipitation to occur. There is some uncertainty on afternoon highs for Friday given increased cloud cover. Current expectations are for most locations along and south of I-70 to reach 60 with mid 60s possible in far SW central Indiana. Near zonal flow aloft and weak low level disturbances will continue to have marginal impacts on Saturday and Sunday. Low level winds will shift back towards the NW for Saturday, dropping highs around 10 degrees. Skies will clear on Saturday though within broad subsidence as the low level ridge axis passes through central Indiana. By Sunday, the ridge will be east of central Indiana, once again placing the region in predominant SW flow. Temperatures should spike back into the mid to upper 50s for Sunday. This SW flow will also be upstream of a stronger cyclone over the plains. Precipitation Possible Early next Week... Weather will become more active early next week, as two more amplified troughs approach from the NW. The first chance of precipitation will be late on Sunday into Monday morning. Significant moisture return within strong SW flow will push Pwat values above seasonal. This along with broad vertical lift should be enough for scattered showers to develop. This should be east of the region by Monday morning, although ensemble members are still varied on overall timing for this event. The next wave looks to move through Tuesday into Tuesday night. This wave should be attached with cold Canadian air and interact with leftover moisture from the initial wave. This will lead to snow on the cold side of the system. Where this low will track is still widely varied, but there is a chance of snow Tuesday night. Confidence in possible snow amounts are still too low to provide value to the forecast at this time.
