Another unseasonably warm afternoon was observed across central North Carolina with most places experiencing high temperatures in the mid- to upper 70s. Record highs were seat at RDU and Fayetteville, both of which hit 78 degrees.

The unseasonable warmth will linger into this evening, great for any outdoor activities.

A cold front working southward through central Virginia will end up near the North Carolina Virginia border later this evening. A very large area of high pressure building into the Northeast U.S. and eastern Canada is nosing southward along the coast. This will force the front to move into the northern North Carolina late tonight and tomorrow morning. It looks as if the front will reach the Triangle, at least the northern half then retreat back northward tomorrow afternoon.

Areas north and northeast of the Triangle would be most vulnerable to this weak surge of low-level cool air. So, areas north of the Triangle should see temperatures running 10-15 degrees cooler than today and cooler by about 10-15 degrees for most of the Triangle. So, places like Roxboro and Burlington could see readings no higher than the 60s for tomorrow. Even though the front will probably reach Durham and Raleigh around daybreak tomorrow the front should retreat back north of Raleigh and Durham tomorrow afternoon. If the front fails to do so readings might also be no higher than the 60s over much of the Triangle.

The large high pressure area to the north forcing this front southward will move east tomorrow. This will allow the large surface high off the Southeast U.S. coast to regain control over the weather across central North Carolina and this will lead to unseasonably warm weather for Saturday into Sunday.

A ribbon of deep moisture extends across the center of the country from Texas into the Great Lakes. This very moist weather pattern will bring rounds of heavy rain that will lead to flooding. This very wet weather pattern will remain well northwest and west of the Appalachians and thus well west of central North Carolina through Saturday.

A pair of eastward moving upper-level storm systems will cause the high pressure area off the Southeast Coast to flatten Saturday night and Sunday. This will allow a cold front to reach central North Carolina sometime later on Sunday or Sunday night. This front should bring showers Sunday afternoon and Sunday night along with cooler, more seasonable temperatures.

A wave of low pressure will form along the front moving into the region Sunday night. This should bring more wet weather Monday.

A large area of dry air ahead of an eastward moving high pressure area will move into the region later Monday night and Tuesday. This should bring dry sunny weather for Tuesday of next week. Temperatures will lower early next week, but still a few degrees above normal.

A large storm system moving into California early next week will bring Southern California some drought relief. This system will force the development of a warm front that will move northward on Wednesday with some late day and nighttime rain. Then a cold front associated with this system will bring more rain and perhaps thunderstorms Thursday of next week.
