Synopsis
Issued at 337 pm cdt Wed mar 20 2019
upper level long wave trough was anchored over greenland with a
significant short wave mving down the back side of the trough into
the upper midwest. Further west, and upper high pressure was
centered over southern alberta canada with a ridge axis exteding
from the southern rockies into the northwest territories. At the
surface, highest pressure rises are swinging through the upper
midwest behind the previously mentioned short wave and attendant
front moving across western and north central ne. Little in the way
of cloud cover was associated with the front in sd NE area and sunny
skies prevailed.

Short term (this evening through Thursday night)
issued at 337 pm cdt Wed mar 20 2019
the aforementioned short wave over the upper midwest will develop
further as it moves into the ohio valley and will be reinforced by a
stronger short wave moving quickly southward behind it. This will
effectively shift the trough axis back to the west and force the
upper ridge to the west toward a negative tilt. Meanwhile low
pressure moving into ca today will begin to become negatively tilted
as well as it encounters the strong ridge across the rockies. While
western and north central NE will be under the influence of the
ridge with warming temps and sunny skies, this flow regime will set
the stage for a longer duration precipitation event for the weekend.

So in short a dry forecast is in place through 12z Friday morning,
with temps exceeding average for this time of year. Have leaned on
the warmer guidance in a blended solution as forecast highs have
exceeded typical blended solutions in the past few days even where
snow melt is occurring. The warmer temps will allow snow melt to
occur across the northern panhandle and northwest cherry county and
along the sd border. With high pressure aloft in place this could
suggest a potential for fog development after midnight and through
sunset, but confidence in this scenarion is not high at this
juncture.

Long term (Friday through Wednesday)
issued at 337 pm cdt Wed mar 20 2019
the 18z NAM is bringing a back door cold front into ncntl nebraska
Friday. This is part of the equation for rain Friday afternoon
through Saturday. The front will help pool moisture across western
nebraska but harm the temperature forecast Friday. If the nam
forecast verifies, highs in just the 40s to lower 50s will occur
across ncntl nebraska. This feature is shown, to a lesser extent in
the canadian model.

Otherwise, there is little change in the models predicted warm spell
Friday through Sunday with temperatures at the h850mb level
remaining to between 5c and 10c. The blended forecast shows high
temperatures in the 50s to around 60 with lows in the 30s to around
40. A strong cold front will move through Sunday night and late
season arctic air will move in for one day. Temperatures should
rebound Tuesday and Wednesday back into 50s and 60s.

The models continue to show an impressive upper low tracking toward
southwest nebraska Friday and Saturday. The SREF suggested about a 9-
hour window of likely to definite rain chances. The model blended
forecast for rainfall totals during this time is generally around
0.5 inches in the form of showers and isolated thunderstorms.

Today's model blend suggested the best rainfall will occur along and
south of interstate 80 and then into custer county. If this rainfall
occurs as projected, the risk of flooding will be low but this storm
system appears to be fairly well organized with strong upslope
winds, above normal moisture, deep saturation and steepening lapse
rates. Thus, the concern for flooding will continue, especially if
the models show the highest rainfall totals developing across
northern nebraska where the ground may still be frozen Friday night.

A second weaker round of light rain changing to snow is likely
Sunday night as a late season arctic cold front moves through.

Aviation (for the 18z tafs through 18z Thursday afternoon)
issued at 1228 pm cdt Wed mar 20 2019
vfr conditions through the forecast period.

High pressure will dominate the area through the period bringing
warmer temperatures to the region. However, this will cause snow
melt across portions of north central NE which may set the stage
for fog formation later tonight in some areas. But because winds
are becoming gusty across the region there is some doubt about the
low level moisture remaining trapped so confidence is not high in
fog formation at this time and hence has been left out of the
forecast for now.

Lbf watches warnings advisories
None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
