Technical Forecast Discussion
Short term (Wednesday 12/26 through Saturday 12/29)
Upper level ridging and associated high pressure move through on Wednesday, leading to cloud clearing and the beginning of WAA. Upper level troughing over the central US will create a strong low pressure system. The shrinking warm front will create chances for rain showers Thursday evening as the frontal boundary moves in. The area will be in warm sector for a short period of time on Friday which will give a brief break from precipitation and a strong surge of WAA as highs look to be in the low 60s. The cold front of the low pressure system looks to push through late afternoon on Friday before dry air moves in ahead high pressure on Saturday.
Long term (Sunday 12/30 through Tuesday 1/1)
Models show a plethora of moisture available during the day Sunday. This looks to be induced from the passing of a jet streak and southerly flow to the west bringing up moisture from Mexico. A possible chance for rain/snow mix will exist Sunday as forcing could interact with moisture to create precipitation. A relatively deep, negatively tilted trough makes its way into the region on Monday. This upper level wave will bring a Alberta Clipper mid-latitude cyclone into the region, promoting snow early Monday and a transition to rain later that day as the warm frontal boundary moves through. The passage of the cold front Tuesday will bring in dry air behind it that will halt precipitation and slowly clear up clouds.
