NWS Norman, OK wrote its last area forecast discussion before the first event at Jan 15, 8:12 PM CST, 1 hour 23 minutes earlier.
Area Forecast Discussion National Weather Service Norman OK 812 PM CST Sun Jan 15 2017 .DISCUSSION... Unfortunately...freezing rain continues early this evening across far northwest Oklahoma where temperatures remain near 32 degrees. Periods of rain will continue into the overnight with temperatures hovering around 32-33 degrees. Widespread showers and storms continue to form farther south across a large part of southern/central Oklahoma. Much warmer air will continue to lift north and west this evening and part of the overnight. Elevated instability around 250-400 J/kg will support very heavy rainfall with a risk of some wind reaching the ground. At this time, supercell structures, like the one south of Dallas, are expected to remain south of the Red River this evening/early morning. && .PREV DISCUSSION... /issued 602 PM CST Sun Jan 15 2017/ DISCUSSION... AVIATION... IFR and LIFR conditions are expected into Monday morning along with rain and, this evening, thunderstorms. Thunderstorms will affect the southeast two-thirds of Oklahoma as they move northeast. Areas of showers and rain will persist until after daybreak Monday. Ceilings will lift later Monday with winds turning west. PREV DISCUSSION... /issued 252 PM CST Sun Jan 15 2017/ DISCUSSION... Moist convection continues to increase across southwestern OK and western north TX this afternoon. As the mid to upper low nears our region this evening through early tomorrow morning, elevated instability and mid level lapse rates will steepen in addition to increasing deep layer shear. The strongest storms are expected across western north TX and southern OK this evening, with another chance for stronger storms over central OK by very late tonight. Small hail and damaging wind gusts could accompany the stronger storms. Further west and northwest, temperatures are remaining near or just below freezing. Therefore, decided to extend the ice storm warning through 12Z Mon with additional precip accompanying the aforementioned low. In addition, some wet snow will also be possible across extreme northwestern OK late tonight through early tomorrow morning near the center of the low. Accumulations could exceed 0.5 inches across Harper Co. Given the amount of ice still present, and the lack of significant snow accumulation, decided against issuing any different headlines. Most of the precipitation will come to an end after sunrise tomorrow, although some rain/snow will be possible on the back side of the low across northern/nw OK through late Monday morning. A warming trend is still expected Tue through Sat as cloud cover clears and heights increase ahead of the next mid to upper low nearing west TX. This low is expected to elongate from the southern TX panhandle through the Baja Wed, with low level moisture increasing across the area ahead of it. Mid to upper moisture, however, appears limited to SE OK. For now, feel like this is the only area where low PoPs are needed for overnight Wed as the low begins to lift over the Southern Plains. Mid to upper shortwave ridging will then follow it for Fri, with fairly warm max temps (mid to upper 60s) expected across most of the FA. After Fri it appears another mid to upper trough will pass over the Southern Plains around Sun. Some precipitation will accompany this feature, although it's unclear how much. Will keep SChc PoPs in for now. Given expected temperature profiles, it appears it will all fall as rain. A Pac cold front will also accompany the trough, dropping temps back into at least the 40s and 50s by Sun. && .PRELIMINARY POINT TEMPS/POPS...
