Area Forecast Discussion National Weather Service Little Rock AR 1252 PM CDT Thu Apr 26 2018 .AVIATION...26/18Z TAF CYCLE Low pres system, centered ovr NE MS, wl cont to provide cyclonic flow/clouds acrs much of AR this aftn. Look for a combo of MVFR/VFR Cigs thru the early evening hrs. VFR conds expected thru the rest of the PD with just some mid and high lvl clouds at times. Breezy N/NW winds this aftn arnd 10 kts, subsiding to arnd 5 kts tngt and early Fri. /44/ && .PREV DISCUSSION...(ISSUED 359 AM CDT Thu Apr 26 2018) Short Term...Today through Friday night Models this morning are showing only minimal differences with the upper level system that continues to produce some occasional showers over central and eastern sections of the state. Given these overall small differences between the models, a blend of forecast solutions is preferred. Latest satellite and radar imagery shows the placement of the upper low quite clearly at this time. Feature is located over southeast Arkansas and matches up very well where the high res models say it should be. Mainly light showers continue to rotate around the upper level low with most models indicating the majority of the precip getting out of the CWA by early this morning. With that in mind, will include a pre first period in the forecast to take into account lingering showers early this morning. Even with the upper low moving away, there will still be plenty of mid to low level moisture to deal with. As such, clouds will be hanging around this morning but some clearing is expected to occur during the day as drier air finally wraps in. Progressive pattern will continue with another weak front moving through the broad cyclonic flow over the eastern half of the nation tonight through early Friday. Models have been steadfast of late in weakening this system as it moves through and this has not changed this morning. Front may squeeze out a sprinkle or two but that should be about it. Another, even weaker boundary will move into northern Arkansas by the end of the period. Another day with below normal temperatures is expected today with highs close to normal for Friday. Long Term...Saturday through Wednesday An upper ridge of high pressure over the Rockies Saturday will provide northwest flow over Arkansas. Areas of low pressure aloft will be over the Great Lakes and west coast. The upper ridge will slowly move east through the weekend and by Monday will be over the Mississippi River. On Tuesday, the western low starts to dig south and turns to the northeast Wednesday. Surface high pressure with dry air will be over Arkansas Saturday. A dry cold front moves into north Arkansas early Sunday but washes out. Dry weather continues on Monday with high pressure moving through the Appalachians. The next chance for showers and thunderstorms will be Tuesday and Wednesday ahead of an approaching cold front. Temperatures will generally be slowly warming through the period. && .LZK Watches/Warnings/Advisories...NONE. &&
