10/27 – Rob Knight’s Friday Afternoon/Weekend Forecast

After a mostly clear start to the day, clouds continue to increase in advance of an approaching cold front. Moisture and rainfall this afternoon Saturday as a cold front swings through the area. A tightening pressure gradient over the forecast area between high pressure over the Atlantic Ocean and approaching trough of low pressure will continue to enhance southerly flow. More widespread activity will likely be nudging into northwestern portions of the area later this afternoon. The bulk of the activity should be rolling through tonight as the cold front moves through. While there doesn’t appear to be a big threat of severe weather, soundings do indicate a small window of opportunity for a few cells to be strong with wind gusts in the 30 to maybe 45 mph range.

No significant changes made to overall thinking about precipitation or ending of the rain with this system as models remain quite consistent. Strong cold air advection will usher in the coldest temps to the area since last winter/spring. Went on the colder side of guidance for nighttime lows Sunday morning with temps dropping into the mid to upper 30s for the northern half of the region. ATTM, there doesn’t appear there will be any locations reach the freezing mark and a slight breeze should keep frost to a minimum. Will have to revisit this again today and Saturday.
