..PREV DISCUSSION... /ISSUED 1004 AM CST Mon Nov 10 2025/

....Synopsis...
Water-vapor imagery this morning shows a longwave trough over the
eastern U.S., while a ridge resides over the West with a series of
disturbances moving east across the Canadian Rockies.  The mid- to
upper-level low over IN this morning and associated cold pocket
yielded a November record low 500-mb temperature (-40.9 deg C)
sampled by the 12 UTC ILX raob at Lincoln, IL.  This upper feature
will move east to NY/PA late tonight.  A cold front over New England
this morning will push east of the coast later this afternoon.  A
couple of lightning flashes may accompany weak convection from
eastern MA into Maine before ceasing later today.  Farther south,
seasonably cool/dry air will continue pushing into the Gulf.
