-- Changed Discussion --
(Tonight and Monday)... Northwest flow remains in place across the area today. This will continue to shuttle dry, cool air into the area. Cloud cover is gradually starting to clear across the south and this trend will continue through this evening into the overnight hours. The combination of colder, drier air and clear skies will result in cold temperatures overnight with lows dropping into the 20s areawide. Wind chills will dip into the teens in the mountains overnight. Surface high pressure will be in place tomorrow and upper level flow becomes more zonal, allowing temperatures to rebound a bit, climbing to near 50 across the north and the mid 50s across the south. With high pressure in control, clear skies and light winds are expected. .LONG TERM...(Monday night through Sunday)... Surface high pressure over the region Monday night and Tuesday will allow for continue dry and cool conditions. A weak frontal boundary will push through the area late Tuesday into Tuesday night. With little moisture in place and minimal moisture or lift associated with the system...mainly expect an increase in cloud cover. So for now...will keep the forecast dry. High pressure builds back in for Wednesday through Friday for continued dry and cool conditions. Another weak system moves through during the weekend. Confidence quite low in details but models again show little moisture or lift attached to the system. At best...expect a few isolated showers across northern areas and over higher terrain. A few flurries may mix in Saturday night.
