Some changes to the forecast this morning mainly for cloud cover. HI-RES models do show good southerly flow into the area with cloud cover streaming in from south to north. Overall however, looping GOES-16 vis imagery over the past few hours reveal a decreasing trend in cloud cover. It seems that the positioning of the high just off to our east is allowing most of the Central Valley and Northward to benefit from downsloping influences, although weak, at 850 mb up 700 mb. It looks like areas north of I-40 should see the most sun today, with the Southern Valley breaking out into sunshine be mid to late afternoon. The extreme Southern Valley and Southwest North Carolina will hold onto clouds the longest. Because of an overall decrease in cloud cover in the forecast, have bumped up max temps today by a few degrees in most places. Will send out new zones for temps and cloud cover adjustment.
