Sunday's high of 46 degrees was 13 degrees above average! That type of warmth has been a very common theme this winter, and the warm trend could very well carry over into the end of February. Temperatures over the south-central Plains and in the south were very close to, if not breaking, records over the weekend with highs pushing the 80's in many locations.
By the end of the week, a strong ridge of high pressure develops over the center of the country. This ridge slides east by the start of the weekend with highs warming close to 50 degrees Friday, and into the upper 50's Saturday and Sunday. It's possible temperatures could come very close to, if not tie, the record high for Saturday. Sunday we may fall just shy of the record, but temperatures in the 60's are definitely possible.
