Alan Crone's Weather Blog: Turning Colder

The pacific front moved across the area early this morning with a few showers.   This boundary is located across Arkansas and is moving eastward away from the region this morning with northwest winds at 15 mph behind the boundary.   A few clouds will, on occasion, flow across the region, but mostly sunny sky is anticipated for most of the day with afternoon highs in the upper 40s and lower 50s.   Clouds will approach the area later this afternoon and tonight.   A cold air mass will move southward later tonight bringing daytime highs back down into the lower 40s Saturday with even colder air likely Sunday into early next week.   Part of the state will experience some snow this weekend but our chances for any measurable snowfall will remain extremely low.

The upper air flow remains largely cyclonic across the nation with a vortex located across or near southeastern Canada extending into the upper Midwest.   A northwest flow on the western side will dominate the inter-mountain region southeastward across the central and southern plains for the next few days.   Several disturbances will drop down through this northwesterly flow bringing the chances for wintry precipitation back to the state.   The first wave arrives later tonight through Saturday morning and midday across northwestern, west central and south central OK.   Some 1 to 2 inch accumulation will be possible, mainly across the west-central part of the state.   Any precipitation that manages to brush far southeastern OK near or south of the I-40 region will remain extremely light and should have no travel impact.   Pittsburg, Latimer, and LeFlore County could experience some very light precipitation Saturday morning through midday.

The 2nd wave will arrive Sunday night into Monday.   The trajectory of this wave could bring additional accumulating snowfall to some of the same areas mentioned above but some light snow may be possible further north.   This 2nd wave could bring some snow flurries or snow showers near the metro late Sunday night into Monday morning. No significant accumulation is likely at this time.

Temperatures Sunday into Monday will be cold with lows in the 20s and highs Sunday in the lower 30s and mid to upper 30s Monday.   We’ll see a minor warm-up Tuesday with a south wind and highs in the upper 40s.   Two more systems may near the state next week including Wednesday and Thursday into next weekend.

Quick short-term summary:   No precipitation is expected today with highs in the upper 40s and lower 50s.   More cold air is likely this weekend with very low snow chances for eastern OK, mainly Sunday night into Monday morning.

Thanks for reading the Friday Morning weather discussion and blog.

Have a super great Friday!
