![]() ![]() Coastal flooding was seen from coastal New Hampshire to southern Maine. Portland, Maine, saw historically high water levels on Saturday morning due to stiff onshore winds. Strong southerly winds flooded portions of New England early in the day. Current Weather Maps Extended Surface Weather Maps Visible Satellite Map US Satellite Map Current US Winds and Gusts More. Our interactive map allows you to see the local & national weather. Power outages due to gusty winds and heavy snow neared 375,000 customers from the Great Lakes to the mid-Atlantic that afternoon. 1 Map US Doppler Radar Map Current rain and snow in the US. See the latest Maine Doppler radar weather map including areas of rain, snow and ice. Gusty conditions also lasted long past their welcome in the Plains and produced blizzard conditions in Iowa, South Dakota and Nebraska through the afternoon. Winds gusted to between 40 and 60 mph from Michigan to western New York. 13, but the winter storm continued to produce snow and gusty winds in the Great Lakes, Midwest and northern New England. 12, as witnessed by The Weather Channel meteorologist Jim Cantore while on camera. Thundersnow was reported in Chicago on Jan. Much lower snowfall totals came in from the shoreline in downtown Chicago and Milwaukee, due to winds flowing off record warm for mid-January, ice-free Lake Michigan water. 11, which helped drop up to 3.7 inches in the city and 7 inches in northern Arizona. Three others were injured in the slide.Ī snow squall moved through Flagstaff, Arizona, on the morning of Jan. A major avalanche occurred and buried multiple people at the Palisades Tahoe resort and a 66-year-old man was the first avalanche victim of the year. 10 and almost immediately destabilized slopes at the ski resorts. Gerri thumped its way into the Sierra Nevada during the afternoon of Jan.

Gerri prompted blizzard warnings for mountain areas of Oregon, Washington and Idaho for the first time since 2012. Gerri's history: Winter Storm Gerri arrived in the Northwest on Jan. The storm was also responsible for rare blizzard conditions in the Northwest and for flooding the coastal Norheast. ![]() Winter Storm Gerri blasted the Midwest with heavy snow and blizzard conditions in mid-January and helped usher in brutally cold air across much of the Central U.S. More importantly, since large hailstones, even through they can have irregular, nonspherical shapes individually, tend to tumble as they fall, their average shape is much closer to spherical and therefore they can be discriminated from heavy rain that might produce a similar reflectivity signature on single polarization radar by the fact that, unlike the large raindrops, the horizontal and vertical polarization reflectivities are almost the same.Sign up for the Morning Brief email newsletter to get weekday updates from The Weather Channel and our meteorologists. This shape makes the large droplets more reflective of horizontally polarized radiation than vertically, so that a differential measurement of the two polarizations can easily distinguish between an area with predominantly small droplets and an area with much larger ones. The classic example of this is the raindrop, which when very small is almost a perfect sphere that scatters similar amounts of energy at either polarization, versus very large raindrops, which take on an oblate shape (on average) that has been likened to that of a hamburger bun. Wind gusts of 40 to 60 mph are likely across much of the Midwest as the storm strengthens Friday. This can give us a very high confidence, for example, as to whether an area in a thunderstorm is composed of heavy rain or hail, and can also give us a reasonably good estimate as to whether the precipitation particles within the beam are principally rain, wet snow, dry snow, snow pellets (also called graupel) or whether the echoes are most likely non-meteorological targets such as birds, bugs, or in extreme cases, tornado debris.Ī dual-pol radar can "see" the different shapes of hydrometeors (raindrops, hailstones, snow flakes, etc.). With dual-pol, we can get the size, shape and variety of objects. In order for a radar to determine the size and shape of an object in the air, it MUST have the capability to send and receive pulses in both the horizontal and vertical orientation. A radar that is not a dual-pol only sends and receives pulses in the horizontal orientation.
