Rain spreads in...



Our next system is organizing in Louisiana this morning, and that low will gradually lift northeast. By later tomorrow, the low will be tracking from eastern Tennessee into West Virginia, meaning we will be on the "warm" side of the system.

For our Monday, rain will spread in with time today, and high temps are a challenge to forecast. I will generally say low to mid 60s for the Piedmont, but it is tricky.

Look for periods of rain tonight through tomorrow. As the wind fields aloft strengthen tomorrow, a few storms could become involved. Although the chance is fairly limited, a few strong to severe storms are possible, mainly tomorrow afternoon. Lows tonight will only settle to near 50 with highs tomorrow highly dependent on rain coverage....60s generally speaking.

Later this week...

The system will be gone by Wednesday with lots of sun and highs up toward the upper 60s. A push of chillier air will briefly arrive for Friday into Saturday with some spots in the 50s for highs Friday. But, a substantial warm-up looks likely by Sunday and Monday....maybe some spots hitting lower 70s again by next Monday.

Cold air?...

Plenty of very cold air will invade Canada and the northern US later this week. Through the first half of Thanksgiving week next week, the upper air pattern will keep that colder air bottled up to our north, and it looks fairly warm around our region. However, in time, the pattern should buckle over the eastern US, allowing the colder air to make it in here. The timing is still a question mark, but later Thanksgiving weekend is a possibility.
