Alan Crone's Weather Blog: Colder Temps Ahead

The cold front is positioned to the southeast of the state this morning and will continue to quickly move away from the region.  This will allow northwest winds at 20 mph this morning before wind speeds will diminish later this afternoon to the 10 mph range.   Cooler temperatures are expected today with highs in the upper 40s and lower 50s for northeastern OK and some lower 50s across the southeastern third of the state.   A re-enforcing shot of colder air will arrive Thursday and last through Saturday morning before another warming trend is expected this weekend into early next week.

The upper air pattern should bring the tail end of a trough across the state Thursday night into Friday morning.   Some data suggest the possibility of a few sprinkles or snow flurries late Thursday night and pre-dawn Friday across far northwestern or western OK.   The odds appear very low due to the dry air mass entrenched across the state.   But the timing of the lift will be concurrent with the highest humidity values across the state.    We’ll mention this low possibility and confine any pops to the west of the metro.    Temperatures Friday may outperform the model stats.   Numbers this morning suggest a high nearing 50 but we’ll go above the mark and shoot for about 53 with west to southwest winds at 10 mph.

The south winds will return this weekend allowing morning lows Saturday in the upper 20s to move into the lower 60s by the afternoon for daytime highs.   Sunday starts in the 40s and will end in the mid-60s with gusty south winds as another storm system will be nearing our area.   Low level moisture may be sufficient for a few showers Sunday afternoon or evening across the eastern third of the state.   This will constitute a 20% chance of showers on the 7 day planner for Sunday night into Monday morning.    A weak boundary may briefly slide southward Monday morning for a few hours allowing morning lows in the upper 30s to lower 40s but daytime highs should rebound back into the lower or mid-60s with a return of south winds by midday to afternoon.

Next week appears to be rather warm by December standards with highs in the 60s and lows in the 40s.   The pattern should bring another system into the state around Christmas Eve or Christmas Day with a chance for showers or even thunderstorms.   A minor cool down may be possible Christmas Day or possibly the following Saturday.   Sunday into early next week remains highly uncertain regarding the specifics, but another strong storm system may be nearing the region.    The pattern will support increasing precipitation chances Sunday into Monday following the Christmas Holiday.   This will need to be watched closely.  More on this one later in the week.

Thanks for reading the Wednesday Morning weather discussion and blog.

Have a super great day!
