Monday Morning Update

I'll keep the discussion on the short side this morning and just hit the highlights.  

Welcome to a short school-work week for some folks, and for others including yours truly, it's a full week combined with some fast Thanksgiving travel.  It appears the weather will cooperate for most folks for most of the week despite two storm systems that will impact part of the area.   

The first system is moving across eastern OK this morning and the second one will be nearing our area Thursday.  The Thanksgiving evening system doesn't appear too robust but some thunderstorms may be possible followed by a nice cool down into the weekend. A more significant cold front may approach the area early next week.  

This morning we're tracking a few spotty showers across eastern OK as a weak mid-level system brushes the area.  The instability factor is very low and we're not anticipating any thunder. Unfortunately, the amount of precipitation that falls this morning will be on the low side and will quickly move eastward through early morning. 

The temps today will stay in the upper 60s to near 70 this afternoon with morning clouds followed by some afternoon sun.  The winds will be out of the today in the 10 to15 mph range.  A fast moving boundary will clear the area tomorrow morning bringing a alight north wind to the region for a few hours Tuesday.  South winds will return for the Wednesday and Thursday time period with a slight increase in low level moisture.  

 Temps for the week will move into the upper 60s and lower 70s with morning lows in the upper 40s. After the cold front crosses the area Thursday evening or Friday morning, temperatures will drop to near 60 for Friday and Saturday afternoon highs.

The upper air pattern may undergo some changes for the next few weeks allowing the polar jet to finally migrate southward.  This will bring a few cold air intrusions into the central and southern plains about every 5 to 7 days.  The big unknown is how the southern stream will respond.  If we get a storm system in the southern stream as the polar jet drops southward, its game on.


The normal daily high is 59 and the low is  38.  

The daily record is 81 from 1908 and a low of 14 from 1937.
