KEY MESSAGE 1... The persistent pattern of dry and seasonable weather will continue over the next 7 days.

The mid and upper level weather pattern through the weekend will be dominated by a high amplitude upper level ridge extending from the western Gulf north into the western Great Lakes with a general northerly flow across the Carolinas. Disturbances in the flow including a series of moisture-starved shortwave troughs will move across the Carolinas tonight and early Sunday. Deep layer moisture will be lacking as precipitable water values will remain low through the period ranging between 30-60% of normal.

A reinforcing surface high pressure system will progress east from the Great Lakes into the the Canadian Maritimes over the next few days. This high will extend into our region behind a dry cold front that will move across the Carolinas this morning. A slightly cooler airmass will arrive today and a northeasterly flow will spread shallow moisture and generate some fair weather stratocumulus clouds across the area during the today and Saturday, especially eastern areas. These will be the first notable clouds in central NC since Monday. Temperatures will generally range near and slightly below average through the weekend.

The mid and upper level ridge will begin to weaken early next week with another short wave trough moving across the region during the middle of the week. The airmass will moderate on Monday and Tuesday with temperatures warming up a few degrees before a slightly cooler airmass arrives for Wednesday an Thursday. Dry weather should continue for through Thursday although there are signals that a more southwesterly flow will result in an increase in deep layer moisture and perhaps the need to consider limited rain chances next weekend.

Reinforcing Canadian surface high pressure will build swd across the Middle Atlantic and Carolinas through the weekend, with related nely surface winds that will become occasionally gusty into the teens to 20 kts mainly at FAY and RWI with daytime heating each day. The nely flow regime will be a maritime-influenced one that will favor an uptick in low-level moisture and related stratocumulus this evening through the weekend. While most stratocumulus will be based above 3000 ft AGL and generally few to scattered in coverage, there is a chance (~30 percent) for short periods of MVFR ceilings, especially each morning.

Outlook: Aside from the aforementioned small chance of sub-VFR ceilings in nely flow this weekend, dry, VFR conditions are expected to persist for at least the next several days.
