Weak upglide will continue Wednesday as the southwest shortwave approaches, but precip should be limited to the southern third of the region where the shallower portion of the airmass is located. All precipitation should come to an end from northwest to southeast on Thursday as the shortwave finally shifts east of the Plains. A slight warm-up is in store Friday into Saturday as the persistent longwave trough across the CONUS shifts slightly east and weak ridging develops overhead. In fact, Friday and Saturday may be the only days we potentially reach 50 degrees or warmer, because a strong arctic front is still progged to blast through the region this weekend. Model discrepancies in the timing of the front, available moisture and just how cold the airmass will be when it arrives are making the forecast for next weekend a challenging one. The EURO is the fastest with the front, pushing it through the area Friday night, while the GFS is 24 hours slower on Saturday night. The current forecast sides more with the neutral Canadian, indicating FROPA on Saturday and quickly falling temperatures Saturday afternoon and evening. With a deep cold airmass in place Sunday through Tuesday, the question will be how much moisture and lift will be around to produce precipitation. At this time, we have leaned towards the cooler side of guidance for late weekend/early next week, but are remaining conservative with moisture and showing only a few bouts with rain/sleet/snow. I am optimistic that as we get through the next couple of days, we will have a much better idea of which parameters will be present and which will not, and have the temperature and precipitation forecast more accurately nailed down. Ether way, after a cold week this week, the start of the New Year looks even colder

Re: Texas Winter 2017-2018
NWS FTW will remain on the fence about next week as for precipitation, as for the temps looks like a few days of highs in the 30s.

Through 102hrs GFS looks remarkably similar to the 0z run. Might be another really cold run

Canadian trending towards the GFS as well...trough stays NE of Hawaii, actually further south allowing the S/W's to dig further South and west, might be more favorable for precip

Storm digging more in the NW that I see, might feature a winter storm. Big cold in Montana and ND

That's what happens when winter gets canceled prematurely before it even starts. Especially when it snowed near the coast just weeks priorEPO always wins
We should probably perhaps focus more attention on the 24hr models. It sounds like they aren't very accurate either though??

29F in Brownsville on the 12z GFS. That would be a very cold night for the state, I'm curious to see if the Euro begins to swing in this direction.

By Friday the big cold front will probably already be entering the US. Tomorrow and Thurs is probably last chance for major shifts, but is unlikely given upstream the event will be unfolding

Right now I have light drizzle with a temp of 37 and a dew point of 34. What a waste of a few degrees.
