Extreme Heat Lingers; Severe Thunderstorms for Portions of the Plains and Southeast; Heavy Rainfall Threats

Gusty winds and heavy rainfall may impact the Big Island of Hawaii as a nearby tropical system passes west of the islands. From the Southwest U.S., Rockies and across the Gulf Coast, heavy rainfall could lead to isolated flash flooding. Severe thunderstorms are expected for areas of the Plains, Gulf Coast and Southeast through Tuesday. Extreme heat lingers for the southern Plains and Southwest. Read More >

Overall, a quiet month. After beginning the month with some snow on the first day, we enjoyed a significant warm spell from the 9th to the 12th with high temperatures in the 60s. Things were quite different by Christmas Day, however, when a brief cold snap took readings down into the teens. Strong low pressure moving through the Great Lakes from the 23rd to the 25th brought light snow and gusty winds to the Ohio Valley. Winds gusted over 40 mph in spots. Locations in central Kentucky along and east of US 127 got around an inch of snow, with some spots in eastern Kentucky receiving half a foot of snow for Christmas.
