Cold Snap Early Next Week

I notice the official high forecast for Starkville next Tuesday is 67, which would be about 5 degrees below normal. I would actually be shocked if the high is that warm next week. A deep trough over much of Eastern Asia the last two days would teleconnect well with the placement of a deep trough over the eastern third of the country by Tuesday and Wednesday. This is hinted at by all models and ensembles to varying degrees with the GFS exhibiting its typical cold bias. It has 850 mb temperatures of -10 C in Starkville Tuesday morning. Brrr! The ECMWF is less agressive than the GFS and delays the cold shot to the middle of next week. The Japanese is in line with the European with the strength of the cold air but is in line with the GFS' timing. The Canadian and NOGAPS are weaker with the trough, but 850 mb temps of -5 C would support temperatures well below normal. The take home message is that next Tuesday appears to be a much cooler day than currently forecast by the NWS. I wouldn't be surprised to see highs nudged down even further over the next few days. Don't put away those winter coats just yet!
