We’re now expecting more winter impacts for a small part of Kansas from this storm system, while the bulk of the state sees a rain event.
The winter watches and warnings have expanded this morning, after latest model runs show the low pressure center taking a more southerly track than was forecast 24 hours ago. The main winter impacts will be west of the low’s track, in the tier or two of counties right along the Colorado line. There’s the full briefing from NWS Dodge City:20181226_briefingSIT
I’m again posting the experimental WSSI graphics for this system, centered on the Goodland forecast office. Please see Monday’s post for more explanation of the WSSI experiment.
I’m sitting at work as I write this, and our helipad cameras in western Kansas are showing the following approximate visibilities (4:51am CST Wednesday):
- Colby: 1/8 mile
- Dodge City: 1/8-1/4 mile
- Garden City: 1/4 mile
This image is from the Aviation Weather Center Helicopter EMS Tool at https://www.aviationweather.gov/hemst
The pink/purple areas are visibilites generally at or below 1 mile. The darker purple is visibility of 1/4 mile or less.
As of 5am Wednesday, the current winter weather advisories for Kansas are as shown below:
Winter Storm Warning (pink): Cheyenne – Decatur – Gove – Graham – Greeley – Logan – Norton – Rawlins – Sheridan – Sherman – Thomas – Wallace – Wichita.
Winter Weather Advisory (purple): Hamilton – Kearny – Scott – Stanton.
Moderate to heavy rain is possible at times anywhere east of the pink and purple areas. Wind will become a factor around and after sunset out west. Please drive carefully!
