AVIATION. 12/06Z TAF Cycle
SCT to BKN high clouds will be seen across N/Wrn AR through Wed night into Thurs morning. VFR conditions will prevail through the period with light Srly winds, and some stronger gusts at Nrn terminals.
PREV DISCUSSION. (ISSUED 544 PM CST Wed Dec 11 2019) AVIATION . VFR conditions will prevail through the entire TAF period. High pressure will remain in control over the region for the next couple of days. Winds will be light and variable overnight. Winds on Thursday are expected to be southerly at less than 10 knots, however, at KHRO and KBPK, winds may exceed 10 knots during the afternoon.
PREV DISCUSSION . (ISSUED 243 PM CST Wed Dec 11 2019) SHORT TERM . Tonight Through Friday Satellite imagery was showing just a few high clouds filtering into western Arkansas from Oklahoma, otherwise skies were clear across the forecast area amidst a weak upper ridge also moving in from the west. Winds were light and variable across the entire forecast area due to widespread surface high pressure in place across the region. It will be another cold night tonight as skies remain mostly clear and winds remain light. However, increasing thicknesses will bring somewhat warmer overnight lows that will generally range from the upper 20s to the lower 30s area-wide.
High clouds will be on the increase Thursday as a shortwave trough of low pressure passes over Arkansas. In response to the shortwave trough, surface high pressure will begin to push off to the east causing a weak southerly flow to redevelop over the forecast area. This will bring a few degrees of warming over high temperatures that will be reached today. Thursday's highs will range from near 50 to around 55. Will see a few more degrees of warming for Thursday night as well. Lows will range from near 30 over the northern higher terrain to the upper 30s over the far southeast. Under mostly cloudy skies, high temperatures Friday afternoon will be fairly similar to those that will be reached Thursday afternoon as low pressure, both at the surface and aloft, moves into Arkansas from the west.
LONG TERM . Friday Night Through Wednesday The extended term will begin with a relatively weak and dry cold front pushing thru the area, while a broad trof aloft pushes across the area. A second system will begin to take shape over the weekend, and this will likely be of more significance, and will likely bring some wintry weather to the state.
A zonal flow pattern aloft in the latter half of the weekend will quickly amplify as a trof drops down across the swrn US. Cyclogenesis will take place on the lee of the Rockies, and a warm front will push northward across the state. Overrunning along the frontal zone will start to bring some precipitation in the vicinity of southern MO and northern AR. Models are in a bit of disagreement as to where this overrunning zone will set up, but it appears there will be a chance for a wintry mix across the northern zones on Sunday morning.
The surface low will move to the east and the GFS and ECMWF both bring it over parts of Arkansas, although the timing is quite a bit different. A number of other models also bring the system over the state, but the timing and forecast location shows a lot of variation. As temperatures drop on Sunday night into Monday morning, another wintry mix could occur across portions of the state - most likely the northern zones.
As the low pushes to the east later on Monday and Monday night, I can forsee the potential for some wrap-around snowfall on the backside of the low, which could potentially bring snow and/or a wintry mix all the way into the southern portions of the state.
The key takeaway at this point in time is: there is a potential for wintry weather across Arkansas in the Sunday thru Monday night time frame. My confidence in a winter weather event at this time is moderate and increasing, however my confidence in the timing, location, and intensity of the event is still rather low. There is a lot that could change as this system begins to take form over the next several days.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
