Full Notification

• A significant winter storm will affect the region. Event timing for the most significant precipitation will be from Sunday night into Monday daytime. Significant amounts of snow, sleet and freezing rain are possible with this storm.
• Event timing will likely impact both the Monday morning and Monday evening commutes.
• 8+ inches of snow are expected where the heaviest snow band sets up. There could be significant amounts of sleet (ice pellets) just to the south of the heavy snow band. There is also the potential for up to one-tenth inch (0.10”) of icing due to freezing rain, mainly during the transition.
• The latest guidance has shifted the most likely area of the heaviest snowfall a bit further south. Whether this is the start of a trend or a one time change remains to be seen.
• Very cold temperatures (especially for early March) are expected on Monday and Monday night. High temperatures will not get out of the 20s in most locations. Normal high temperatures are in the mid to upper 40s. So we will be 20 or so degrees below normal. Wind Chill values will be in the teens in most areas with single digits in northern and western areas. Overnight lows will be in the single digits and teens.
• Wind gusts up to 40 mph are possible near the Atlantic coast late Sunday night through Monday.
• Minor tidal flooding is possible, given today’s new moon. High tides to watch are the ones on Monday. Widespread minor tidal flooding is not anticipated at this time.
