The 90-day outlooks indicate no major change in thinking as the northern U.S. is where the cold/snowy risk is located with the Northeast likely biased milder due to the warm Great Lakes and northwest North Atlantic while the southern states are warmer and drier than normal. Interesting is the southern U.S. drought forecast by NOAA influenced mostly by La Nina. What will become an issue next spring/summer is potential northward expansion of drought from the southern states into the Great Plains.
