NWS Little Rock, AR wrote its last area forecast discussion before the first event at Dec 31, 11:58 PM CST, 2 minutes earlier.
Area Forecast Discussion National Weather Service Little Rock AR 1158 PM CST Tue Dec 31 2019 .AVIATION...01/06Z TAF CYCLE VFR conds are expected to cont thru the PD. Look for high lvl clouds to cont incrsg ovr the region. Some lower clouds wl start to work into the FA fm the SW aft 02/00z, but any CIGS shld rmn at VFR lvls. Light winds thru the early mrng, wl incrs fm the S on Wed at 5 to 15 mph, with higher gusts ovr N AR. /44/ && .PREV DISCUSSION...(ISSUED 224 PM CST Tue Dec 31 2019) SHORT TERM...Tonight Through Thursday Night Current WV sat imagery and mesoanalysis data indicate cyclonic flow exiting the CONUS over the Upper Great Lakes, with broad anticyclonic flow moving Ewrd over the Srn periphery of the Natural State. Strong sfc high pressure will move Ewrd through Tues, promoting settled conditions with seasonably warm temperatures across the forecast area. Wed, quasi-zonal H500 flow will yield lee troughing, amplifying rapidly through the day and driving potent sfc cyclogenesis. Winds will shift to prevailing Srlies through Wed, providing increased moisture transport and WAA, with temperatures in the mid-50s over much of the state. Rain chances remain limited to far S/Ern AR Wed evening, with increasing cloud coverage from south to north expected. By Thurs, an anomalously moist airmass with PWATs in excess of 1- 1.4" will exist in the warm sector of the aforementioned low. An amplified wave will provide strong forcing for ascent with upper diffluence and a strong jet max ejecting over the region. Low-level isentropic ascent will also aid in driving widespread rain showers over most of AR starting early Thurs morning and persisting through the end of the short term and into the long term. Overall, sfc based instability looks to be limited to non-existent, however some marginal elevated CAPE and a few isolated thunderstorms may be possible over S/Ern AR. Rainfall totals through the end of the period will range from 0.25" over N/Wrn AR to 1-1.25" in Cntrl/Srn AR. LONG TERM...Friday Through Tuesday A 500MB trough will be moving through the Plains region, with the base of trough over TX/LA. On the surface, a Low will be centered over Ern OK, with southerly flow transporting warm air and plenty of moisture into the ArkLaMiss region. The Low will track E/NE with a surface cold front. The front will move through the state Friday. This system will bring rain chances through Saturday. Precipitation coverage will include a large portion of the state Thursday and become more confined to the Nern and Ern portions of the state by Friday morning, as the Low tracks NEward through MO, and the cold frontal boundary exits the Ern AR border. Temperatures Friday morning will be in the lower 40s in Nern AR to the lower 50s in Sern AR. Highs Friday in the mid 40s to upper 50s. The Nern few rows of counties could see a mix of wintry precipitation Saturday early morning, as moisture wraps around the Low tracking through MO/IL and surface temperatures across Nern AR reach freezing temperatures. Lows Saturday morning in the upper 20s across Nern AR to the upper 30s across the S. No accumulations or impacts are expected at this time. Temperatures will warm to above freezing and precipitation will exit the state by Saturday, mid to late morning. Highs Saturday in the lower 40s to lower 50s. The upper trough will have moved into the Ern CONUS by Saturday evening, while the upper ridge enters the region, tracking east as it loses amplitude. Surface high pressure will begin to set in beginning Saturday, expanding SEward through the weekend. Meanwhile, NWerly wind will transport colder and drier air into the state through Sunday morning. At that time, the high center will have moved SE of the state, returning S/SWerly flow which will increase temperature and moisture. Lows Sunday morning in the lower to mid 30s. Highs Sunday in the mid 50s to lower 60s. Temperatures will remain near average through the rest of the period. High temperatures Sunday through the rest of the period will be in the mid 50s to lower 60s. Lows will continue to be in the 30s. Some model guidance depict an upper trough and surface Low pressure system approaching from the W as early as Tuesday morning. Others suggest different tracks and coverage, so will keep PoPs low toward the end of the period until forecast confidence improves. && .LZK Watches/Warnings/Advisories...NONE. &&
