785 FXUS64 KAMA 111138 AFDAMA Area Forecast Discussion National Weather Service Amarillo TX 638 AM CDT Thu Oct 11 2018 .AVIATION...12Z TAFS... MVFR/IFR conditions will be likely at all TAF sites over the next 24 hours. Low clouds and patch fog will be in place over the Panhandles. East winds will continue to provide upslope flow and may even allow for some drizzle to occur later this morning, and into the evening. Winds will shift out of the south later this evening in the 10 to 15kt range. Weber && .PREV DISCUSSION... /Issued 407 AM CDT Thu Oct 11 2018/ DISCUSSION... The story of the forecast period will be the potential increasing for a widespread freeze across the Panhandles on Sunday night, and the increased potential for accumulating snow on Sunday night into Monday. Will still not get into snow amounts, but some models are trying to hint at a significant accumulation to the northwest Panhandles, with lesser amounts to the south and southeast. Cold front continues to move further south than previously forecast. As a result we can expect low clouds to linger over the Panhandles today. This will inhibit heating from the sun as the cloud deck looks to be fairly thick. Upslope flow will be in play as well and we could see some drizzle across the western and central Panhandles this afternoon and evening. Afternoon highs have been cut back about 5 to 10 degrees from the previous forecast. Looks like highs in the upper 40s to lower 50s will be in play. It's possible the official highs might occur right around midnight, as we still expect thick cloud cover, but south winds will start to kick in and might cause a late evening temperature increase. As the warm front pushes north across the area on Friday, expect that highs will return to the 60s to lower 70s. Very limited precipitation chances are in store on Friday, but have chance pops across the southwest if the remains of Hurricane Sergio make it there in time. By Saturday the southern and eastern Panhandles are now where the pops will be focused as the track of Sergio looks to now be centered over Lubbock's area, v.s. previous tracks over the Panhandles. And after Sergio exits to the northeast a strong cold Canadian air push will make it's way to the Panhandles. This is where we will continue to focus our energy on the forecast, as the potential for moderate to heavy snow across the northwest is in play, a widespread hard freeze across the entire Panhandles will be possible, along with lighter accumulating snow potential. The cold air is expected to linger through Tuesday morning with warm air to return Tuesday afternoon and to the rest of the extended. Right now have gone mostly dry for the extended as it looks like high pressure will try to take over thereafter. Weber && .PRELIMINARY POINT TEMPS/POPS...
