Friday Morning Update

Well, we finally made it to Friday!  And...drumroll….No winter precip will occur today!  We'll see a mix of mostly sunny conditions with a few clouds along with northwest winds around 10 mph .  Highs will stay in the upper 30s to lower 40s for many locations.   

The precipitation maker is gone from the state but residual moisture along the far northwestern and northern areas will present dangerous roadway conditions in some areas this morning.  While roadways in Tulsa should be in fine shape, there will be spotty but significant ice on the roadways in Pawnee, Osage, Nowata, and Craig counties this morning.  Some roadways may also be icy in extreme East Central OK closer to the Arkansas state line.  Please use caution when traveling on secondary roadways in areas northwest and north of Tulsa. 

Our upper air pattern will bring a fast but weak wave over the area Saturday morning that may produce a sprinkle or a brief flurry across the south central portion of the state, but nice weather will be the rule for the day.  I have had a 10 pop in for this probability this week, but the last run of the EURO seems to indicate areas to our south would be the better location.  Temps will start in the upper teens or lower 20s and be followed by highs in the mid to upper 40s Saturday afternoon.   

The next wave will quickly drop into the southern plains Sunday morning.  This will allow winds to increase speeds out of the southeast in the 15 to 25 mph range by Sunday afternoon.  RAW NAM data indicates temperatures should move from the 30s Sunday morning to the lower 60s Sunday afternoon.  Some locations across southern OK may it the lower 70s before a surface boundary moves across the area late Sunday night into Monday morning.  This system may be able to produce a few showers or storms near or east of highway 69-75 followed by some snow across far northern OK or southern Kansas.  The timing of the Sunday system is faster with the NAM and GFS, but is slower with the EURO data.  I'm inclined to side with the slower EURO at this point but will mention a late Sunday night start time.  Well need to watch this system closely for the potential of winter precip Monday midday.  

Another wave should approach the area between Wednesday or Thursday and could also lead to some wintry issues.  This system has not been consistent in model data runs with both GFS and EURO waffling back and forth with different solutions.  I'll keep the chance in the forecast at this point.

The high in Tulsa yesterday was 36.

The daily normal average high is 55 and the low is 33. 

Records include a high of 90 from 1996 and a record low of 11 from 1963.

I'll be discussing the weather this morning on numerous Radio Oklahoma Network stations across the state through the noon hour.
