Area Forecast Discussion . UPDATED National Weather Service Norman OK 1048 PM CST Sat Dec 7 2019

AVIATION. 08/06Z TAFs. Primarily VFR forecast, with a chance for MVFR visibility across central-northern Oklahoma 12Z-18Z. Veered lower level flow will hamper any fog development, but after sunrise near surface trough across northern Oklahoma, best chances for fog/stratus development mainly east of KOKC up toward KPNC. Also, will include mention of LLWS first part of forecast given intensifying low level jet.

PREV DISCUSSION. /issued 532 PM CST Sat Dec 7 2019/

AVIATION . 08/00Z TAFs. VFR conditions expected to prevail at most sites through the forecast period. Area of fog/stratus will be possible late tonight and tomorrow morning near and east of Interstate-35 as low level moisture increases sufficiently. Little in the way of model consensus for anything significant and will keep previous forecast trend of potential of MVFR for a few hours after sunrise from KOKC/KOUN up to KPNC. KPNC will have the higher likelihood for fog/stratus development.

PREV DISCUSSION . /issued 348 PM CST Sat Dec 7 2019/

DISCUSSION . High pressure draped across the southern plains and eastern CONUS is generating southerly winds and moisture advection over our area. Latest mesonet data shows a plume of moisture (as indicated by 40-45F dewpoint temperatures) being advected across southeastern Oklahoma. This moisture will continue along its trajectory tonight bringing a chance for patchy fog during the early to mid morning hours tomorrow. Winds will be rather strong for radiation fog. However, fog that develops will likely be due to moisture advection. Have increased the areal coverage for patchy fog to include central and east-central OK in the grids. There is some uncertainty as to the duration and coverage, if any fog develops at all.

The upper level ridge will push eastward ahead of a longwave trough that is currently located off the west coast. Subsequently, NW-ly flow aloft will back WSW-ly tomorrow as the trough axis reaches the western Rockies. Meanwhile, a 500mb jet max develops over AZ/NM and a surface low develops over SE Colorado and TX/OK panhandles. Low level SW-ly flow coupled with moderately packed isotherms signals WAA, and coupled with the resulting downslope flow, will warm temperatures nicely on Sunday - especially across SW OK and western north TX - where max temps will reach the mid 70s.

A cold front will bring cooler temperatures on Monday. The next chance for rain will be Monday evening into Tuesday morning across the southern two tiers.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
