Yesterday, tornadoes caused damage from Alabama into Georgia. Surveys are ongoing by the National Weather Service to determine their strength. Massive hail damage also occurred in these areas, destroying vehicle windshields and punching through roofs. Today, thunderstorm activity is expected to form and become plentiful ahead of a frontal boundary moving across primarily Florida, but clipping Georgia and South Carolina. Wind shear across this area should be supportive of stronger storms, with all severe threats: hail, damaging wind gusts, and some tornadoes. The environment will likely promote severe bowing segments within linear thunderstorms, causing a stronger risk of high winds and tornadoes. A tornado watch is currently in effect in Florida until 7:00 PM EDT and tornado warnings have already been issued. Our Weather Radio app can help those in the area stay aware of this severe weather risk. 

WeatherOps is forecasting another nor'easter for the New England area. Substantial deepening of a low-pressure area is forecast as it tracks along the Atlantic Coast over the next couple of days, eventually making its way into Newfoundland within 72 hours. While winds further inland will be more subdued than the previous nor’easter, gusts in the 40-50 mph range will still be possible along coastal regions from New Jersey into New England. Meanwhile, more snow can be expected from the mountains of West Virginia, northeastward, into Maine as the storm transitions to all snow by Wednesday morning. Snow may be more far-reaching than the last nor’easter as snow bands may extend into portions of Ohio, with Indiana and Kentucky receiving some minor amounts. Snowfall ranges from 2-4 inches will be fairly standard across the Northeast region with areas of heavier snow bringing 6-12 inches and locally higher totals. Snow should taper off from south to north quickly early Thursday morning into Thursday evening, with widespread clearing by midnight Thursday.

An area of low-pressure is expected to slowly move towards California, bringing moisture across the region and promoting very heavy rainfall from south of San Francisco through Los Angeles. Rainfall amounts of 3-5 inches widespread are likely, but localized totals of more than 6 inches will be possible, with coastal slopes and the foothills seeing potentially 8 inches or more. With this threat will come the risk of widespread flash flooding and mudslides as the heaviest rain is expected to affect the same area where the Thomas Fire occurred. Mandatory evacuations, ordered for parts of Ventura and Santa Barbara counties, are started at noon local time and will last until at least Thursday evening.
