![]() ![]() See my report here for the maps that prove this. When a storm gets stronger, the mb are lower numbers, which we say are ‘dropping’.Ī Bomb Cyclone is defined as a storm dropping more than 24 mb in 24 hours, or more than 1 mb per hour for a day. In short, a storm is low pressure, and a deeper storm has lower numbers of atmospheric pressure we measure in millibars (mb). Both will be validated over the next few days. In my prior report I answered two common questions about this event. I’ll be up early to see if “stuff” is advancing or not. I expect there may be some wind advisories and wind chill advisories issued for Friday into Saturday morning. The winds will be ferocious with gusts in metro areas to 40 mph and up to 60 mph in the mountains. I expect Wind Chill Advisories for some of the area given these numbers. It might be hard to believe this is real, and even if it’s over zealous, it will be getting very cold in a hurry! The freezing line now reaches the coast by noon, while Baltimore drops to the lower 20s and teens to below zero farther west. It’s not the accumulation, it’s the support for wet roads to freeze that is the big story! Snow may only last a half hour to up to 2 hours. The arrival of the arctic air keeps getting sooner. Let’s Focus On The Temperatures, because the snow will be minimal. In fact, metro areas may get it by 9 AM to 10 AM. The main issue is that THE FLASH FREEZE is very likely and will arrive BEFORE NOON. I will have an update on the specific timing later. Since Rain is expected Overnight, let’s Jump to Friday Morningĭue to my limited time, these are maps I shared last night. It will reach us EARLIER on Friday Morning. Part 2: The Arctic Blast is producing a blizzard in the Great Lakes today. I would share the same concern for Northern Baltimore and Harford Counties in Maryland to Southern Pennsylvania through York and Lancaster. It is possible not all of the counties get slick, but parts of them will. In Maryland, Howard and Carroll County were added. But it does show snow and ice impacts for the same counties I mentioned above. This is the best model we have and it was missing the light snow and sleet at 5 and 6 am, so it’s hard to tell how well it will handle the rest. We are on the fine line between snow and ice inland, to just a cold rain for the cities near the Bay and Delmarva. This is Part 1 of the storm and is just beginning to fill in on the radar. These are areas that may get icy when this precipitation moves in. I’ve highlighted the freezing line in blue. High Winds And Wind Chill Advisories are for Friday and I expect more will be added for the rest of our region.Ħ AM Radar And Temperatures 6 AM Local Temperatures I would share the same concern for Northern Baltimore and Harford counties in Maryland to Southern Pennsylvania through York and Lancaster.įlood Watch for metro Counties along the western shore of the Bay.Ĭoastal Flood Advisory off the Atlantic Beaches. Winter Storm Warning where the mountains may see over 3 inches of snow. It is possible not all of the counties get slick, but parts of them will! ![]() In Maryland Howard, Carroll County, and Montgomery Counties were added. Please be careful into western Howard, Northern Baltimore and Harford counties as well. I expect there will be more issues expanding east before 8 AM. School Delays: In Maryland – Carroll and Frederick Counties are on a 2-Hour delay. This is developing this morning and will be expanding through the commute and bus routes, and my concern is that the later half could get troublesome INLAND! City and Bay areas will be just rain. It is important to note that ground temperatures are much colder that last week, so where air temps are at freezing, anything falling may very well stick on the ground. The next result for this Part 1 of the storm has already brought in bands of flurries and sleet to central Maryland and Southern Pennsylvania. The focus on this report is for this morning as the faster timing I have been mentioning has been getting even faster. ![]()
