A brief warm spell and back to colder than normal temperatures.

.SHORT TERM.../Tonight through Sunday night/
Issued at 315 AM EDT Fri Apr 6 2018

Models are close enough that the model blend initialization
was accepted for most items.

The surge of colder air aloft and the upper wave will still be
influencing the area at the start of the Tonight period. The NAM and
short term hi-res models focus the best precipitation chances across
the northern and central forecast area early in the period with the
global models farther south.

The NAM has strong frontogenesis across the Interstate 70 corridor
at 00Z, while the RAP and GFS weaker and farther south. If the NAM
ends up being right, this could create some banded heavier
precipitation in the colder air, which would lead to a quick couple
of inches of snow for parts of the I-70 corridor. With most models,
including the SREF mean, keeping the best forcing to the south, will
not buy into the NAM solution at this time. Will have to keep an eye
on how things develop though.

By sticking with the other models, will go high chance to low likely
category PoPs this evening across the south, diminishing overnight.
Precipitation type looks to be a mix of rain and snow south, with
some snow central and north. Went with a dusting for much of the
southern half of the area, with perhaps up to a half an inch some
areas farther south.

Cold high pressure will build in for Saturday and Saturday night,
keeping conditions dry. A low pressure system will move into the
area Sunday afternoon and night, bringing more rain and snow. There
is the potential for 1-2 inches of snow for some areas with this
system. Winter will just not give up.

The model blend looks reasonable for temperatures.

.LONG TERM /Monday through Friday/...
Issued at 250 AM EDT Fri Apr 6 2018

A fairly active period is expected through the long term, with weak
systems bringing chances for precip early in the week and then again
later in the week. Rain chances will increase and temperatures will
warm significantly later in the period as a stronger low pressure
system organizes near the end of the long term, placing the area
solidly in the warm sector. While this may bring a brief period of
the sorely missed warmth from this unsatisfying spring, guidance
beyond the period suggests this will be only temporary.

Blended initialization required relatively few minor tweaks.
