Latest Area Weather Summary for Northwest Arkansas
Weather Summary was last updated at 10:30 a.m. cst Friday, February 28, 2020

Breezy westerly winds and clear conditions prevailed across much of Northwest Arkansas at mid-day. After a cool start to the morning, temperatures this afternoon will steadily warm to our seasonal normal, reaching the middle 50s in most locations. Temperatures tonight will be near our seasonal normal as well with light and variable winds. Otherwise, a very dry atmosphere will remain in place across Northwest Arkansas through Saturday while a high pressure ridge builds in from the west, resulting in a clear sky.

The surface pressure gradient will tighten on Saturday into Sunday ahead of our next storm system, causing southerly winds to increase. Warm air advection and sunshine will allow temperatures to climb into the 60s by Saturday afternoon. The atmosphere will still be dry, with dewpoints staying primarily in the 30s, which will cause minimum relative humidity values to plummet into the 20 to 30 percent range during peak heating hours. The subsequent meteorological conditions will pose an elevated fire danger.

Meanwhile, an upper level low will spend the weekend dropping southeast along the California Coast within the subtropical jet stream, while a northern stream low pressure system progresses eastward along the U.S. - Canada border. The northern system will help push a cold front southward through the Plains. Ahead of the front, moisture will return in earnest as the Gulf opens up on Sunday. Conditions will be mild and windy Sunday afternoon, but higher relative humidity's should help to mitigate the overall fire danger.

On Monday, the upper low will turn east and begin traveling along the U.S. - Mexico border, while the cold front crosses the Plains and into Northwest Arkansas by Monday night. Isolated warm, moist advection showers will be possible Sunday night and during the day Monday as moisture levels steadily climb. Strengthening lift as the upper low draws nearer may eventually result in isolated thunderstorms by Monday afternoon, focusing mainly along the frontal boundary.

Our pressure falls should become most noted Monday night and Tuesday as the upper level low approaches the Big Bend area. Unfortunately, this is the time frame in which model guidance begins to disagree with regard to the speed at which the upper level system will advance farther eastward, with the gfs being more progressive compared to both the ecmwf and Canadian. Fortunately, however, the timing difference is only about 12 hours, which is not that much considering we are looking at days 4 and 5 of the forecast. The question is whether activity becomes most widespread Monday night into Tuesday, or Tuesday into Tuesday night. Either way you look at it, the most widespread precipitation and highest rain chances will be centered on Tuesday.

This weather system will then exit to the east Tuesday night, bringing an end to the wet weather by midweek. Upper level high pressure ridging will develop overhead in its wake, resulting in slightly above-normal temperatures and dry weather for the latter half of next week.

...This Day in Weather History...

In 2017, Fayetteville had their warmest February on record.
