1/28 – Rob Knight’s Friday Morning “Cold Front” Forecast
Weak cold front will blasts through the area this afternoon and evening, but the airmass is too dry to produce precipitation. Not anticipating any weather systems in the wake of this disturbance through the weekend.
Main concern will be temperatures. Mid and high cloud cover should hang around a good bit of the day, but do expect to see some sunshine late in the day. Overnight lows pretty much in the middle of the guidance envelope tonight and tomorrow night. Northern areas are expected to remain above Hard Freeze criteria (25F), and the coastal counties are expected to remain just above freezing. Beyond Saturday night, a moderating trend in temperatures will commence, with highs in the mid and upper 60s, perhaps approaching 70 on Sunday in some locations.
A potent upper level disturbance will sweep through the forecast area Monday into Tuesday. Monday will see return flow increase in advance of the system, and this will allow for an increase in low level moisture and high dew-points into the region. However, some lingering dry air in the mid and upper levels of the atmosphere will produce a strong capping in the atmosphere Monday afternoon. As a result, only some marine layer cloud development is expected beneath the cap. The onshore flow regime in the low levels will allow for warmer than normal temperatures with highs expected to climb into the 60s and possibly lower 7os.
