A Blizzard Warning is in effect from 10 AM today through 6 PM Monday, with rain and snow turning to heavy snow by 3 PM and blizzard conditions tonight (15-21 inches overnight, gusts to 46 mph). Travel will become very difficult to impossible from mid-afternoon on.
- 01 Blizzard Warning (Extreme severity) in effect from 10 AM today to 6 PM EST Monday. It calls for 18-25 inches of snow and gusts to 45 mph, and says travel should be restricted to emergencies only.
- 02 The alert's listed 'to' time (10 AM) conflicts with its text (10 AM today to 6 PM Monday). The longer window in the text was used.
- 03 6-10 AM: temperatures 34-35F, a 35-54% chance of light rain and snow, and light winds of 3-9 mph. These are the least hazardous hours, though roads may be wet or slushy.
- 04 10 AM-3 PM: rain and snow likely (61-73%), temperatures 35-36F and winds up to 14 mph, with deteriorating conditions.
- 05 From 3 PM: heavy snow, with temperatures falling to 32F by 5 PM, which raises the risk of slush and ice.
- 06 From 6 PM: heavy snow with blowing snow, a 93-100% chance of precipitation, and winds of 15-24 mph with gusts to 46 mph. Snowfall rates may exceed 2 inches per hour.
- 07 Blowing snow may sharply reduce visibility, but no numeric visibility data was provided.
- 08 Wind chills as low as 12F tonight. Stranding would be dangerous, and downed branches or power outages are possible.
Avoid all non-emergency travel today. If you must drive, the safest morning window is 6-9 AM, before the warning starts and while precipitation chances are under 50%. There is no safe evening window, since heavy snow and blizzard conditions last from 3 PM through tonight. Your best option is to complete any essential trip before about 1 PM, when conditions are still rain and snow near 35F, and be off the road well before 3 PM. If you are caught out, carry a winter survival kit, stay with your vehicle if stranded, and call 511 for road conditions.
