DISCUSSION

KEY MESSAGES: 1) A cold front moving in today will bring temps below freezing tonight for most locations tonight.

2) Above normal temperatures are expected to persist until a cold front arrives late Wednesday night.

3) Gusty northwest winds are expected Thursday.

4) Temps look to hold near normal through the weekend.

WEATHER PATTERN OVERVIEW:

A weak cold front will be moving south through the CWA late today. Little sensible weather will be noticed with it except for maybe a wind shift. Temps tonight are expected to drop below freezing, except SW Phillips and Petro county/zones should stay above freezing tonight.

An upper ridge to our west will muscle in another surge of warm air later Wednesday before a cold front drops south late Wednesday night. Inversions will keep the northern valley locations from rising above the 30s, but the southern locations should rise into the 40s, 50s and possibly the low 60s (Petroleum county).

The cooling trend continues into Friday with highs Friday near 20 northeast to near 40 southwest. A slight uptick in temperatures can be expected over the weekend with nearly steady temps into early next week. Dry conditions are expected.

FORECAST CONFIDENCE & DEVIATIONS: Used NBM for most forecast elements except: - Bumped pops up slightly for tonight, that gives some mainly snow chances in the Northeast. - Blended with NBM90 for winds Thursday, from 12z to 06z Friday. TFJ
