Delta Differences

Courtesy of the Weather Underground

For those familiar with the Delta Junction area, the plot at the left from the Weather Underground nicely illustrates the competing airmass regimes. From Fort Greely northward the Tanana Valley jet is blowing, draining the cold pool still sitting over the upper Tanana Valley. Just to the south, along the Delta River. chinook warmed airmass is in place. If/when the southerly flow breaks through look for temperatures to jump 20F or more in a few minutes at Fort Greely and the immediate Delta Junction area.
