NWS Little Rock, AR wrote its last area forecast discussion before the first event at Jan 31, 11:40 PM CST, 20 minutes earlier.
Area Forecast Discussion...Updated for Aviation National Weather Service Little Rock AR 1140 PM CST Fri Jan 31 2020 .AVIATION... Slow clearing will occur overnight/Saturday morning, with conditions mostly VFR. In parts of central/eastern Arkansas, some locations may have brief MVFR conditions due to low clouds before clearing occurs. Any fog will be patchy and generally light. Winds will be light west/northwest overnight, and west at 6 to 12 mph on Saturday. (46) && .PREV DISCUSSION...(ISSUED 246 PM CST Fri Jan 31 2020) SHORT TERM...Tonight Through Sunday Still contending with abundant low lvl moisture/clouds acrs the FA today. However, some BINOVC have been noted ovr parts of cntrl and ern AR. Mid aftn temps ranged fm the mid 40s to the mid 50s. Expect clouds and patchy fog to prevail acrs the region tngt. A weak trof wl swing acrs the region tngt, with a gradual wind shift noted with this feature. Clouds wl finally dcrs in earnest on Sat as high pres blds into the Mid-South. By Sun, the sfc high wl shift S of AR, allowing SW winds to return and a nice warm up. Highs on Sat wl be in the 50s, with 60s and lower 70s common Sun. && Long term...Sunday night through Friday While overall the medium range models continue to show some increasing agreement between them, it would appear that the GFS solution is playing catch up with the ECMWF. As such, I will continue to lean towards the more consistent ECMWF. Period initiates with a weakening upper trough over northern Mexico with a more significant upper trough located over the Pacific NW. Pacific trough will morph into a deep upper low with surface ridging over the eastern gulf shunted even further east. Upper low will deepen resulting in a increasing southerly flow and increasing low level moisture. The result will be temperatures remaining well above normal Monday and Tuesday with widespread highs in the 60s. The primary trough will move through the Intermountain West late Sunday into Monday. Broad southwesterly flow in the mid/upper levels will overspread the region with large scale forcing for ascent increasing and subsequently an increasing chance of showers late Monday and into Monday night. Upper trough does take on a bit of a tilt as it swings through the central plains on Tuesday night and into Wednesday with precipitation chances continuing. There is a small window for a few stronger thunderstorms over the southeast, aided by low pressure developing along the associated front. Overall, severe chances are not very high but still worth watching as the event unfolds. Upper system will kick out quickly with the cold front moving through the state Tuesday night. In its wake, much colder air pours back into the state and our brief flirtation with spring will come to an end. Stop me if you have heard this before but with storms of this nature, this time of the year, its a timing versus moisture race for any winter weather. Still have some very light snow across parts of the north and northwest but it appears there is too much of a gap between the the departing moisture and arriving cold air for any real winter precipitation. After a somewhat chilly Wednesday and especially Thursday,temperatures will moderate at the end of the period and beyond. && .LZK Watches/Warnings/Advisories...NONE. &&
