🌀 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!

SNOW AND ICE THREAT INCREASING

Jan 8, 2019
3 min read

Winter Storm threat increasing for some parts of NC, the potential for snow and ice has increased throughout the week. Lots of questions if this storm will be the same as the December storm? No one storm is the same so it will not be the same, will have the same trends. Lots of hype regarding this storm before I get started, models are changing each run and no one really knows exactly how it will set up yet.


WHAT: Cold air will move into NC Thursday and Friday setting up for Winter Weather this weekend, if you are reading from the coast or eastern NC snowfall is not expected another cold rain event is expected. Just thought I would say that now so you don't have to read through it. One thing you need to have a good snowstorm is cold air in place first, we will have that but lots of other things come into play. The real unknowns per usual start. The exact track of the low? Is there two or one low pressure? How much moisture? Rain/snow line location? All of these questions will be ironed out in the coming days.


Below is my first guess based on a verity of models of where snow, sleet mix or just rain will fall. I feel pretty confident that accumulating snow will fall from Greensboro and points west. East of Greensboro will be a battle ground of snow, sleet, and freezing rain and just plain rain. East of Raleigh will be mostly rain. The Triangle and points east, models remain very unsure exactly how the rain/snow line will set up or occur, some areas could see plain rain or snow. East of i95 sorry looks to be just plain old rain. This can change over the next few days as of right now this is the best map.

TIMING- Precipitation moves in Saturday afternoon and evening, event lasts through the day Sunday ending by evening hours.


The trends for today among the models have been a North and West movement of the low pressure system. Wintery weather looks possible, but the types and amounts are still up in the air. Pages posting snowfall maps and models are just trying to get likes and clicks, major news channels across the state are also doing that. Don't fall for hype most winter storms in NC change before they actually occur, number 1 rule 3 days out usually the most accurate.


Important to remember, that small differences in the storm track make a huge difference. Track 3 along the coast favor snow for everyone west of the track. Track 1 (inland track) favors rain for most of everyone but the mountains. The track between (Green-White) favor an icy mix mess for Triad and foothills, while mountains see a beautiful snow and triangle sees a cold rain with points to the east.


Many ingredients are coming together will ultimately impact our storm. The questions, of course, are what track will it take, how much cold air is available, what type or types of precipitation will we see, and how much. These details will be tough to nail down until we get a little closer. Let me remind you, many snowfall amounts maps are being rapidly shared. Snowfall maps greater than 3 days out are simply wrong, no one knows how much snow or ice will fall yet. Thursday short range models come into play which will give us a better idea.


HOW MUCH: I know the real answer everyone wants to know is how much snow/ ice will come down. Be patient here, with it being 4+ days away and different solutions among models. Lots of time to go and lots will change, no real to panic or freak out, this system is very complex and changing thus no reason to hype it.
