Thursday Morning Update

Posted: Updated:

We expect mostly sunny and cool conditions with highs in the mid to upper 40s.  A fast but weak moving wave arrives tomorrow with a few flurries at times across extreme NE OK.  

The relatively cool air mass will continue to circulate across the state as the upper air trough remains anchored to our east.  This upper air pattern will remain through Saturday before a quick return to warmer conditions occurs Sunday and Monday.  More cool air is possible by Tuesday and Wednesday next week.  

The main upper air trough located from the Great Lakes into the middle Tennessee Valley while a ridge is developing across the far southwestern U.S.  This creates a northerly to northwesterly upper air flow across the central plains including our local region.  Cold and dry air situated across the eastern half of Canada into the upper Midwest will continue to be located near and northeast of our area.  This air mass will reside across the state for the next few days, and may be re-enforced with more cold air by Friday into Saturday before the warm up begins Sunday afternoon.  

This northerly and northwesterly upper air flow will also bring a few weak mid-level disturbances across the state from time to time, including a slightly stronger wave Friday.  This Friday wave will more than likely produce some light snow showers Friday night into Saturday morning across the eastern third of the state into northwestern Arkansas, but the coverage and duration of the event will be small.  I'll more than likely not include a probability on the map, and may resort to "mentions only" until we draw closer to Friday night.  This wave will act very similar to the one that produced light snow showers yesterday morning across far NE OK and SE Kansas.   

Sunday as the mid-level ridge grows across the far southwestern U.S., a fast moving western U.S. trough will slide across the intermountain region and cause surface pressures to fall across southeastern Colorado.  This will cause our surface winds to respond from the east and southeast Sunday afternoon in the 10 to 25 mph range.  Temperatures at the 5000 ft. level will warm quickly across western OK, and our surface readings in NE OK may approach the mid-50s Sunday afternoon.  

 Monday we'll have a chance to hit near 60 before the cold front and low pressure area quickly slide across the state.  Low level moisture will be suppressed to the Gulf of Mexico and we'll not include a chance of showers or storms with this frontal passage.  Cooler air will reside Tuesday and Wednesday across the northern third of the state before more seasonal air arrives a week from today.  

The high in Tulsa yesterday was a whopping 48 recorded at 1:59pm.

 This normal high is 57 and the normal low is 35.

Daily records include a high of 82 from 1972 and 1932.  The daily record low is 6 from 1962.

I'll be discussing our weather today with Dan Potter and the KRMG Morning News.

I'll also be broadcasting state wide and regional weather reports through the noon hour on numerous Radio Oklahoma Network affiliates across the state.
