NWS Little Rock, AR wrote its last area forecast discussion before the first event at Apr 30, 11:33 PM CST, 27 minutes earlier.
Area Forecast Discussion National Weather Service Little Rock AR 1233 AM CDT Tue May 1 2018 .AVIATION... High pressure is just east of Arkansas. Low clouds in the southwest are moving northeast. Expect scattered low clouds at the central and south sites this morning. Otherwise high cirrus will drift through the state. VFR conditions will continue through the period. && .PREV DISCUSSION...(ISSUED 608 PM CDT Mon Apr 30 2018) DISCUSSION... Updated to include the 00Z aviation discussion below... AVIATION... Some breezy SRLY winds will be seen throughout the period...especially on Tue afternoon across NRN and NW sections of the state. However...VFR conditions will be seen through the period. PREV DISCUSSION...(ISSUED 247 PM CDT Mon Apr 30 2018) SHORT TERM...Tonight Through Wednesday Other than scattered CU across west central and southwest sections, clear conditions continue across the forecast area. Clear conditions will prevail during the overnight hours. Near to slightly above normal temperatures daytime temperatures are expected during this period. A southwesterly flow pattern will develop over the mid south during this period, as an western U.S. upper level trough deepens as it moves slowly eastward. Best chances for any convective development will appear after the short term period. LONG TERM...Wednesday Night Through Monday Quite a bit of low level moisture will be pooling across the state on Thursday, in advance of an approaching frontal boundary on Friday. Aloft, a deamplifying trof will be sliding across the mid section of the country. At the moment it looks like there will be only modest height falls associated with this trof on Friday and beyond, and not much upper level support for convection. There has been a lot of buzz on social media about the potential for severe weather west of here on Thursday (which looks like a valid concern), and a bit of speculation about the possibility here on Friday. For the most part, I do not think the chances for severe weather are very in Arkansas. First off, the approaching front is relatively weak and does not contain much of a cold punch behind it. Second, the instability does not look very impressive, and as mentioned above, the upper level support will be very weak. A few isolated severe storms? Certainly not out of the question. Anything more than that looks rather unlikely. I think rainfall will be widespread, but I do not anticipate enough rainfall to cause significant problems. The front does not look like it will hang up across the state, and weak high pressure should move in fairly quickly behind it. Beyond Friday the area will be on the eastern edge of a weak ridge. Temperatures across the state will not see much change after the front, with temperatures staying close to climo. && .LZK Watches/Warnings/Advisories...NONE. && Aviation...51
