Another Frost Advisory, weekend warm up

RALEIGH, N.C. (WTVD) -- First Alert-Frost Advisory West & North of Raleigh: A Frost Advisory is in effect until 9am today for Person, Granville, Vance, Warren, Halifax, Alamance, Orange, Durham, Franklin, Chatham, Moore, and Lee Counties. Frost could harm sensitive outdoor vegetation. Sensitive outdoor plants may be killed if left uncovered.

Good morning! The coldest air of the season, so far, is in place this morning. Out-the-door temps range from the low 30s to low 40s. Expect a chilly and mostly sunny afternoon with highs in the upper 60s to low 70s. With temps dropping into the upper 30s and low 40s for most tonight, frost potential will be limited.

Canadian high pressure will expand over the Mid-Atlantic through the end of the week and will remain in place through early next week. Conditions will remain dry through Monday. Highs Friday will be in the upper 60s. Weekend highs will be in the 70s, with lows in the 50s.

In the long term, our dry October looks to continue as night pressure remains in place for much of the East Coast through early next week. Highs will be near 80 Tuesday and Wednesday.

A weak cold front will spread across the Northeast into the midweek, but any precipitation with this boundary struggles to develop this far south. Some temperature impacts seem possible after this front passage, but timing and intensity of this front after traversing the Appalachians remains to be seen. As of now, this appears to be our best chance of precipitation through the end of the month.

Tropics:

1. Near the Leeward Islands (AL94): A poorly-defined trough of low pressure is producing disorganized showers and thunderstorms extending from the northern Leeward Islands northward for a couple hundred miles over the adjacent Atlantic waters. Development, if any, of this disturbance should be slow to occur while it moves quickly westward to west-northwestward at around 20 mph, passing near or just north of the Virgin Islands and Puerto Rico today, then near Hispaniola and the southeastern Bahamas on Saturday. By late this weekend, further development is not expected due to strong upper-level winds.

* Formation chance through 48 hours...low...10 percent.

* Formation chance through 7 days...low...10 percent.

2. Western Caribbean Sea (AL95): Widespread showers and thunderstorms continue across the northwestern Caribbean Sea in association with a broad area of low pressure that is gradually becoming better defined to the north of eastern Honduras. Environmental conditions appear conducive for some additional development over the next day or two, and a short-lived tropical depression or storm could form before the system moves inland over Belize and the Yucatan Peninsula of Mexico on Saturday. Regardless of development, locally heavy rainfall is likely across portions of Central America and southern Mexico through the weekend.

* Formation chance through 48 hours...medium...50 percent.

* Formation chance through 7 days...medium...50 percent.

Have a great day!
