October 23-27, 1862, an unseasonable snowfall event not seen again until 1869 swept through the Plains, Midwest, Ohio Valley & parts of the Northeast.
A strong system, it had quite a bit of wind & a large area of accumulating snowfall. Snow showers/flurries were reported as far south as Memphis, northern Mississippi, Alabama to Rome, Georgia on the storm’s backside.
5″ of snowfall was measured in Lafayette with it on October 26 with 4″ at Cincinnati & Zanesville, Ohio, while St Louis reported 4″. Over a foot was reported in the higher elevations near Charleston, West Virginia, but flooding rainfall occurred at Harper’s Ferry, West Virginia. Meanwhile, flooding was reported in parts of New England with much of Concord, New Hampshire’s 5.40″ of rainfall for the month falling with this storm. No snowfall occurred with it there.
Interestingly, the reports in Kentucky & at Cincinnati indicate that the rain & snowfall was greatly appreciated as it had been a very dry summer & fall. In fact, the entire south & parts of the Midwest suffered through a significant drought in 1862.
Snowfall was reportedly light at Milwaukee & very minor at Dubuque, Iowa.
At Lafayette, temperatures fell into the teens by early morning on October 27 as skies cleared, but all of the snow reportedly melted on October 27.
From southeastern Indiana to the Mid-Atlantic, another snowfall occurred November 7. 2-4″ was general from Louisville, Kentucky to Washington, D.C. to Delaware.
It is still very warm as of 11:45 p.m. with temperature at 68-72. Even where it has been raining, temperatures are still 69-71.
This, after 77-81 today & gusts to 39 mph.
One band of showers & a few t’storms has moved through our central & northern areas. That has moved north & northeastward, leaving just a few spotty showers in its wake.
Additional showers & t’storms are lining up with the surface cold front from Oklahoma to Illinois.
This will pass through late tonight-Tuesday morning.
0.20″-0.50″ still looks like a good total for the area with a couple of isolated locations of +0.50″.
Current rainfall totals are in second image below.
