Further increases in confidence for an impactful winter storm are noted across the Carolinas with greater uncertainty still farther up the coast.

Take this storm seriously.
Moderate to major impacts are expected from the Central US through to the Northeast through the weekend.
- Hazardous to impossible driving conditions are expected. Avoid travel if at all possible.
- Widespread closures and disruption to infrastructure may also occur.

I’d be very careful with posting snow maps for the weekend storm this far out.
There’s still significant uncertainty with the amplitude & progression of both SW US + north stream troughs, which drives both the event duration & how far north heavy snow expands into the Northeast.

Wildfires can spread quickly — by the time one is nearby, you may not have much time. Have an evacuation plan, and prepare an emergency supply kit ahead of time. Listen to local officials for emergency information and any evacuation orders.

Impressed with the resilience of #Senyar… looks like a coherent circulation may have made it across #Malaysia. Nice radar coverage showing the last 24h revolution as it crossed from the Malacca Strait ➡️ South China Sea.

What is poor practice during Hurricane season is also poor practice in Winter Season.
Do not share deterministic models forecasts >5-7 days out. Snowfall maps are an especially poor choice of model graphic to share with much lead time.

There is a reason why most (unfortunately I can’t say all) #meteorologists don’t show extended range ensemble forecasts for a reason. Even if a disclaimer like “this is not a forecast” is given, the forecast is still being shown and could be misinterpreted as such. 😒

Looking at how the NWS offices back each other up. Severe weather and flash flooding in the south central US next couple of days.

Love observing the local effects of terrain on the boundary layer fog in California. For instance, Check out the drainage into the San Luis Reservoir where low level flow is forced to curve anticyclonic into the local saddle point of the Coastal Range.
Makes for some photogenic views!

Hurricane Melissa produced the fastest hurricane winds to be recorded by a dropsonde, verified by reviewing data at NSF NCAR! Hurricane Melissa’s 252 mph wind gust surpassed the previous record from Typhoon Megi over the Western Pacific in 2010, where a dropsonde measured wind gusts of 248 mph.

Seems like the #Aurora is already visible over a large chunk of the CONUS tonight thanks to the #CME's over the last few days from a couple of significant X-class solar flares.
