NWS Little Rock, AR wrote its last area forecast discussion before the first event at Feb 4, 5:52 PM CST, 2 hours 30 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Little Rock AR 552 PM CST Tue Feb 4 2020 .AVIATION... Frontal boundary will continue to move southeast and out of Arkansas during the evening hours. Convergence along the boundary will allow for continued showers with it, along with an isolated storm or two. This will diminish later this evening, as the boundary shifts east of Arkansas. However, precip will develop again to the northwest and move into Arkansas late tonight into Wednesday Morning as an upper level system affects the state. With colder temperatures moving in, precip will likely be a freezing rain/rain/sleet mix in the northwest by early afternoon through the end of the period, with all rain elsewhere. Conditions will remain mvfr or lower, especially in areas that see precip. && .PREV DISCUSSION...(ISSUED 243 PM CST Tue Feb 4 2020) SHORT TERM...Tonight Through Thursday The cold front is pushing slowly SE through central sections of AR early this Tue afternoon...with widespread SHRA ongoing along and behind of this front. Ahead of the front...temps continue in the mid to upper 60s...but coverage of convection has been limited so far. Temps drop into the 40s and 50s behind the front...with some 30s now showing up across the far NWRN counties. Best chances for SHRA will remain across the NRN/NERN half of the CWA through the rest of the afternoon as a weak upper disturbance lifts NE over this region of the state. Further SW...mainly just frontal forcing will be seen to trigger convection...with overall coverage of precip much less. Coverage looks to be further hindered further south due to some warming in the 850-700 mb layer noted on forecast NAMNest soundings in this region of the state. Even so...keep chance to likely POPs in the SERN third of the CWA as the front pushes SE through this area. There may be a few TSRA across the whole area...with best chances across this SERN third of the CWA where temps are warmest. Cannot rule out an isolated strong to briefly SVR storm across the SERN counties...but overall SVR threat is low at this time. Coverage of precip decreases tonight as the front pushes further SE into far SERN AR. Some isolated to scattered SHRA may be seen overnight...but better chances for organized SHRA will be seen on Wed. Even so...pockets of rain...or DZ may be seen overnight. Temps may get cold enough overnight across the higher terrain of the NWRN counties to see some light freezing rain or FZDZ. However...precip rates should be low enough overnight to only see some minimal impacts...especially since these areas were in the 70s and 80s over this past weekend. More persistent and widespread precip will be seen during the daylight hrs on Wed as a new upper disturbance lifts NE in the SW flow aloft...with convection developing near an 850 mb front across NWRN AR. Temps should remain near or even below freezing in some of the highest terrain...so may see an initial wave of RA/FZRA mix...which could also see sleet mixed in occasionally. Depending on how intense the precip is...and how cold temps are...this may result yet another round of measurable ice accumulations Wed for the higher terrain of the NWRN counties. Winter Wx headlines may need consideration over the next 12-18 hrs if this looks to become a more likely situation...with ice amounts of over one-tenth possible in the highest terrain. During the same period...SHRA and some TSRA will be possible across central and SERN portions of the CWA Wed. The front should have moved far enough SE of the CWA to see the SVR threat remaining low. However...if this front slows enough...there may be a small window during the daylight hrs on Wed across the far SERN counties to see a strong storm or two. However...better chances for any strong to SVR storms will be SE of AR. Drier conditions will be seen for Thu as SFC high pressure moves into the region. There may be some lingering rain across far SERN sections of the CWA...but most areas should remain dry. However...temps will be in the 30s and 40s for highs...with a NW breeze. LONG TERM...Thursday Night Through Tuesday A large upper trough will be over the central U.S. to begin the long term period with an upper ridge over the west coast. Northwest flow aloft will be over Arkansas through Saturday. Sunday will be a transition day as the flow becomes zonal then a southwest flow sets up for Monday and Tuesday. Another upper low dives into the Pacific Northwest Saturday night and becomes closed off over southern California late Sunday, then moves into Texas Tuesday. Dry conditions are expected in Arkansas Thursday night as a cold front moves into the Plains. The front will move through Arkansas Friday night and Saturday with chances of mainly rain, though snow may mix with rain in the north Friday night into Saturday morning. No snow accumulation is expected at this time. Precipitation ends over the area Saturday afternoon. High pressure moves into the state Saturday night and Sunday. Rain chances return Sunday night and continue through Tuesday. Isolated thunderstorms will be possible at times. Below normal temperatures are expected through Sunday and above normal temperatures return on Monday. && .LZK Watches/Warnings/Advisories...NONE. && Aviation...57

Isolated storms could become strong in southern and eastern sections of the state this afternoon and evening. Much colder air will begin arriving from the northwest tonight. .DAYS TWO THROUGH SEVEN...Wednesday through Monday As colder air continues building across the region Wednesday and Wednesday night, a wintry mix of precipitation is expected mainly in the Ozark Mountains of the northwest and a few higher elevations spots in the Ouachita Mountains. At this time, snow accumulations of one to two inches are in the forecast in the far northwest. Elsewhere in the mountains, amounts will range from nothing up to maybe a half inch at some locations. Freezing rain may precede the snow, with up to a tenth of an inch of ice in places. The forecast may change depending on how much moisture is available when it becomes cold enough to support snow and ice. To monitor the situation, continue checking forecasts for updated information. .Spotter Information Statement... Spotter activation will not be needed. && Visit NWS Little Rock on the web.
