Morning Fog

The fog has formed overnight with some locations near and below freezing.  This has prompted a freezing fog advisory for portions of the state with dense fog advisories posted for other locations.

The Tulsa metro will continue to see the dense fog and temperatures may drop into the upper 20s before sunrise.  This would create a possibility of freezing fog which is fog that freezes on contact with exposed surfaces including bridges and overpasses.  Drivers are urged to use caution this morning and allow for extra commuting time.  The fog will begin to thin out as the temperatures move into the mid and upper 30s after the 10am hour.

The brief intrusion of winter is over, at least for a few days.  Spring like storms will be nearing the area tomorrow morning with highs in the lower 60s Wednesday afternoon.  Another cool down will be likely this weekend, but the temperatures will be near or just slightly below the seasonal average.

The snow totals were higher to the northwest of the Tulsa metro with some 3 and 4 inch reports from Shidler to near Ponca City.  The official Tulsa total was 1.7 inches with some 2 inch totals near the northern sections of the viewing area.  Locations south of I-40 received about an inch of snow but mid-morning rains quickly eroded the snow as temperatures moved into the upper 30s.  The official high yesterday was 37F degrees recorded at Tulsa International.

The next upper level system is rapidly drawing near to the area and our winds will be increasing from the southeast later tonight into Wednesday morning.  A surface area of low pressure will rapidly form across northwestern OK and move eastward Wednesday afternoon and evening.  A dry line type feature will form across the western part of the state and move eastward by Wednesday afternoon with a chance of a few surface based storms Wednesday afternoon and evening across far eastern OK.  Some scattered early morning elevated storms will be likely tomorrow morning across eastern OK and western Arkansas as the moisture attempts to return across the state.  These elevated storms will be capable of producing a few hail storms tomorrow morning.

After the Wednesday system, a fast moving wave will push another surface boundary through the area Friday.  There remains some discrepancy in the 5000ft level regarding the temperatures and this could support a colder forecast than our current numbers, especially for Saturday and Sunday.  Some additional changes to this portion of the forecast will be possible.

The GFS data suggests a slight chance of showers Saturday and possibly Monday, but we'll keep the forecast dry for another cycle before adding any probabilities.  I'll take this approach due to the inconsistency found in the extended models.
