Area forecast discussion, Feb 14, 11:56 AM CST, 2 hours 55 minutes before
Area Forecast Discussion National Weather Service Little Rock AR 1156 AM CST Sun Feb 14 2021 .UPDATE... Updated to include the 18z aviation discussion. .AVIATION... A mix of MVFR/IFR conds will prevail across AR this afternoon. Conds are expected to deteriorate to IFR/LIFR through the afternoon/evening with the arrival of a winter storm from the Srn Plains. SNPL is mentioned over Srn terminals, initially this afternoon, but will change over to all SN joining other TAF sites also expected to be SN through the TAF period. Accumulation of several inches of SN is expected at all terminals with PL accumulations possible at KPBF and KLLQ. Expecting moderate to heavy SN at times across the aforementioned two terminals between 12z-18z Monday. && .PREV DISCUSSION...(ISSUED 603 AM CST Sun Feb 14 2021) AVIATION...14/12Z TAF CYCLE MVFR CIGS were noted acrs the area this mrng. Wintry precip is expected to overspread the area fm the W as the day progresses. Most areas wl see mainly SN, with a SN/PL mix expected over portions of central and southeast AR. Expect OCNL IFR conds in some area late in the PD. /44/ PREV DISCUSSION...(ISSUED 415 AM CST Sun Feb 14 2021) SHORT TERM...Today Through Tuesday Focus in the short term will cont to be on the first storm sys that will bring accumulating snow/some sleet to the FA starting later today thru much of Mon. No changes were made to the going headlines that are still in effect. Skies were mostly cloudy acrs the FA this mrng, with temps ranging fm the single digits ovr NW AR, to the teens and 20s elsewhere. Already seeing sub-zero wind chill reading ovr parts of N AR early this mrng. Overall fcst trends have not changed with this fcst cycle. Initial round of precip is expected to slowly overspread the area fm the SW late this mrng and thru the aftn hours as a lead upr impulse lifts Newd acrs the region, with most of the accumulating snow focused ovr the NW half of the FA. We could actually see a dcrs in the overall snowfall rate this evening as the upper support shift N of the FA. A stronger upr sys wl then lift thru the region later tngt and Mon, bringing with it another round of snow. Model have tended to shift the main axis of accumulating snow/sleet assocd with the upper sys to the SE half of the FA. Model soundings still show a shallow warm layer aloft for periods of sleet to occur ovr parts of cntrl/SE AR at times, which could affect overall snowfall amts. All of the precip is still expected to taper off fm the SW later in the day on Mon. As far as accumulations go, 3 to 5 inches are fcst for locations generally along and NW of the I-30/Highway 67/167 corridor. To the SE of this axis, 4 to 7 inches of snow/sleet is expected. As has been stated many times before, there wl likely be some adjustments to some of these amts as the storm track could still deviate ovr the next 24 to 36 hours. Bitterly cold temps wl impact the region in the coming days. Highs wl be mainly in the teens and 20s the next few days. Lows tngt wl drop into the single digits and teens. The coldest mrng wl still be on Tue. With fresh snowcover, and high pres bldg into AR, lows will plummet to sub-zero readings ovr N AR, with single digits common elsewhere. Brutally cold wind chills wl fall to below zero at most locations. The weather on Tue wl be very cold and dry, but another winter storm wl impact the Natural State by the middle of the week. LONG TERM...Tuesday Night Through Sunday As soon as the first system exits the area, attention will then turn to another H5 trough that will be approaching the area, bringing another round of wintry weather to the state. ECMWF solution continues to be slightly faster versus both the GFS and the CMC but overall impacts on the sensible weather would be minimal. As such, a blend of forecast solutions is preferred this morning. All data continues to show a highly amplified pattern to start the period with deep troughing and very cold air remaining over a good part of the continental United States. Another strong piece on upper level energy will be moving out of the Rockies and into the nations mid section by Wednesday morning. Set up is very similar to what will be happening in the short term with moisture overspreading the region and into the arctic air. This will result in widespread accumulating snow over the region mainly in the Wednesday/Wednesday night time frame. Thermal profiles are once again supportive of a wintry mix over the south and southeast with both freezing rain and sleet possible. However, amounts and location varies between the models at this time and likely to change from current thinking moving forward. With so much going on in the short term, decided to just use a blend of model snow outputs with enough wintry precipitation to be worrisome. Ended the precipitation from west to east Thursday as the upper system pivots to the northeast. There is so good news to pass on though. Once this system exits the region, models all agree that the upper flow will be flattening out and the arctic air mass will start to pull out with temperatures slowly moderating next weekend. Until then, temperatures will remain well below normal. Look for highs only in the 20s Wednesday but warming back into the 30s for Thursday with some 40 degree readings returning by Friday. Overnight low temperatures will remain downright cold with Friday morning appearing to be the coldest morning with widespread lows in the single digits and teens. && .LZK Watches/Warnings/Advisories...

Hazardous Weather Outlook...UPDATED National Weather Service Little Rock AR 238 PM CST Sun Feb 14 2021 ARZ003>008-012>017-021>025-030>034-037>047-052>057-062>069-151100- Boone-Marion-Baxter-Fulton-Sharp-Randolph-Newton-Searcy-Stone- Izard-Independence-Lawrence-Johnson-Pope-Van Buren-Cleburne- Jackson-Logan-Conway-Faulkner-White-Woodruff-Scott-Yell-Perry- Polk-Montgomery-Garland-Saline-Pulaski-Lonoke-Prairie-Monroe-Pike- Clark-Hot Spring-Grant-Jefferson-Arkansas-Dallas-Cleveland- Lincoln-Desha-Ouachita-Calhoun-Bradley-Drew- 238 PM CST Sun Feb 14 2021 This Hazardous Weather Outlook is for a Large Part of Arkansas. .DAY ONE...Through Tonight Bitterly cold wind chills will continue through tonight and into Monday. Coldest wind chill readings over northern Arkansas are expected to range from 10 to 15 below zero through tonight, with some colder values possible. Over central Arkansas, coldest wind chill readings could fall to around five below zero, while the southern portions of the state could see wind chills near or a little below zero. A strong storm system will continue to move through the area, with widespread snow and possible sleet. The snow could be heavy at times. This will result in treacherous driving conditions. If travel is necessary, use extreme caution and allow extra time to reach your destination. .DAYS TWO THROUGH SEVEN...Monday Through Saturday Wintry weather will be continuing across the state Monday morning as the storm system pulls away from the region. Precipitation will be mainly snow except for a wintry mix continuing over the southeast part of the state. The precipitation will be ending from the west during the day Monday before coming to an end Monday evening. Total snow and sleet accumulations of six to eight inches are possible in areas near and east of the Interstate 30 and Highway 67 corridor, with totals of four to six inches generally west of this area. This potential for wintry weather will create significant impacts across most of the state. While some differences exist in the exact placement of the where the heaviest of the winter weather will fall, confidence continues to steadily increase on a significant winter storm. Please refer to the latest forecasts as details regarding the exact impacts become more clear. Much colder air will be over the state Monday and into the middle of the week as an arctic air mass remains over the area. This will be the coldest air of the winter so far and possibly some of the coldest we have seen in many years. Low temperatures Monday through Wednesday mornings will be in the single digits and teens with parts of the north likely dropping below zero. Highs Monday and Tuesday will mostly be in the teens and 20s. Expect wind chills to be even more significant with wind chills dipping well below zero for a good portion of the area Monday and Tuesday mornings. An additional round of winter weather will be possible on Wednesday and into Thursday with more accumulating snow likely. Several inches of snow could fall with more of a wintry mix once again over the southeast. .Spotter Information Statement...
