🌀 Tropical Update: Good afternoon, everyone. I'm sure everyone is sick of working on this fine Tuesday, so as you take your scroll break from work, I thought you'd love to read my tropical update. In true fashion as we head toward the start of schools/colleges, the tropics are coming alive, and this year is no different. I am, and forecasters at the National Hurricane Center are monitoring two main areas for potential tropical development in the Atlantic Ocean and two areas in the Pacific Ocean, with one showing a potential threat to Hawaii.

In the Atlantic, we have an area of disturbed weather in the North Atlantic moving away from the United States that has a low chance 20% of some Tropical Development over the next 5-7 days, but does not pose any threat to NC!

Down in the Main Development Region of the Atlantic, we've had several tropical waves that are moving off Africa over the next 5-10 days, and some are trying to show signs of development. There is now a 70% from the National Hurricane Center that a Tropical Depression or Storm will develop in this area. There remains high wind shear and dry air, so it'll face an uphill battle as it moves generally westward across the Atlantic. Since the system has not even developed, let's take models with a grain of salt and not jump to too many conclusions, but the threat to North Carolina at this point is rather low. So there's no reason to worry at this point.

Image 2: Is a graphic I created to give you an idea how long it takes tropical systems to travel across the Atlantic Ocean (NOT A FORECAST), just an example. This location is 10-14 days away, and it may not even survive the trek across. There could be some enhanced moisture to parts of the Caribbean Islands which they very much need.

Over in the Pacific, there is an area of disturbed weather over 1k miles east southeast of the Hawaiian Islands that has a high chance of becoming a Tropical Depression or Storm. Interests in the Hawaiian Islands should closely

monitor the progress of this system.

I'll keep you posted all season long; nothing to worry about right now in NC!

❄️ Winter Storm Update Snow/Ice Maps: Well, it looks like we're going to have our next Winter Storm in North Carolina! Over the last months, weather forecasters in North Carolina have been busy. I've spent the last several hours pouring through countless data, looking at atmospheric profiles, and using my experience from past events to make my snow/ice maps below. I'll explain the forecast for each region below; some areas will have an impactful winter storm, while others will have more of a nuisance event. The majority of the state will see some impacts; regardless, even the thoughts of snow/ice will cause travel problems. It is North Carolina, after all.

📌WHAT: This looks like a classic Miller A storm setup; we will have a low forming across the Gulf and intensifying off the East Coast of the United States, pushing moisture inland Wednesday into Thursday across North Carolina. High pressure to the north will supply cold air, which will allow for parts of North Carolina to likely experience Winter Weather. After reviewing the data, we will have a low come up out of the Gulf and develop and strengthen off our coast during that period. Pieces of energy will transfer from the west across the state, and help develop the low-pressure system off the coast. This will set up a dry slot across parts of Western NC, so I only think there will be rather limited snowfall across the Western part of the state due to lower moisture content.

⚠️WHAT WILL FALL: Region by Region:

1-3 Inches (Dark Blue): This area is built into two sections. I am expecting 1-3 inches of snow across parts of Central North Carolina into the Triad and then back across most of the mountains. Areas across Central NC have the greatest risk of seeing 1-3 inches of snow and sleet mixing in with the red-hatched area. Due to warmer air aloft working, which will result in snow melting then refreezing into sleet. Sleet cuts down on snowfall totals but makes for a mess with travel. There is a high bust potential here, and the area from Raleigh and Greensboro northeast could end up with some more snowfall when it is all said and done, but the impacts are the same. Don't get caught up on the exact amounts of snow, impacts to travel will be the same.

Across the mountains, 1-3 inches are expected for most areas, but some areas in the (NW favored) mountains could see more snow of up to 3-5 inches in spots. The mountains are used to this snow, but impacts to travel are likely as well.

4-7 Inches (Dark Purple): This area appears to be the sweet spot across parts of the Northern portions of the state into Northeast North Carolina. 4-7 inches of mostly all snow is expected here; impacts to travel are likely here.

Dusting-1 Inch of Snow/Sleet (Light Blue Area): This area will see a lighter amount of snow and sleet mixing in where the red-hatched area is. There will be travel problems especially further east, where Freezing rain is going to mix in.

⚠️ Freezing Rain: Freezing rain is likely across the Sandhills and Southern to Southeast parts of the state into parts of Eastern North Carolina. If it is raining, but temps are below 32°, that is Freezing rain. A light glaze is expected across all of the sandhills and area east and south of Raleigh/ Charlotte, and more significant icing is expected across the bright pink areas with 0.05-0.30" icing likely from Fayetteville to Goldsboro to Greenville to New Bern/Jacksonville. Areas with higher icing could see scattered power outages and down trees; this is something we will watch for.

⏰: Snow/Ice: Will begin Wednesday morning across the Western part of the state and spread east into the late morning into the early afternoon hours. Snow/ice/rain will wind down from west to east through late Wednesday night into Thursday morning. There could be some scattered snow showers around on Thursday morning as well.

UNCERTAINTIES: As with nearly every winter event, forecasting winter weather is complex and hard. I've looked through all the data available, and there are still a good number of uncertainties regarding this forecast, such as exactly how much moisture works and where the snow/sleet/freezing rain will set up. Don't take these snow maps literally, as changes will likely occur over the next 24 hours. I'll continue to watch the forecast trends, work to be transparent, and change the forecast as it happens. I'll likely have an updated snow/ice map tonight if we see changes in the forecast data and trends.

👀: The Bottom Line: I think the odds of an impactful Winter Storm, both from snow and ice, are increasing; we will have to monitor for impacts Wednesday and Thursday across the state. Forecasting is a science; please don't panic. Forecasts are going to be all over the place due to the high uncertainties. I think some areas across parts of Central/Eastern NC could end up with an impactful snow/ice storm. There is no reason to raid the grocery stores, but if you're across parts of Central/Western NC and parts of Eastern NC, be aware of potential impacts tomorrow into the end of the week; thanks to cooler air anything that falls will stick around into the weekend. I'll walk you through the forecast for the next 24 hours, sharing updates as I see fit. That'll help you and your family make decisions with the best data I have and experience forecasting winter weather events over the last 9 years.
