Area Forecast Discussion
National Weather Service Hastings NE
1238 PM CDT Mon Aug 19 2019

.SHORT TERM...(Today and tonight)
Issued at 418 AM CDT Mon Aug 19 2019

A little bit of stratus and fog have developed mainly in the western
part of the forecast area, but there is also a little in the east.

The stratus and fog has been a little slow to develop. The winds are
lighter in the areas that have some stratus and fog. Development of
fog this morning is still a bit of a question. The winds should help
to keep the fog from developing as much, but the temperature/dew
point spread is close enough that it could still develop. Have kept
some fog and stratus development, but since it is slower to develop
it may not produce as low of visibilities.

Once any fog that does develop dissipates this morning, expect a
warmer day. Winds should turn to the south and increase a little.
This will bring in additional low level moisture with increasing dew
points and temperatures will be a little warmer as well. Heat index
values will get to around 100 degrees in north central Kansas.

There is a weak upper level wave that moves through the area
tonight. Some models have some precipitation with it and some do
not. Those that do have different locations. Have a slight chance
for thunderstorms in the northwest for a time this evening, but not
sure how much there will be. Later tonight, there could be some more
patchy fog. Dew points will rise noticeably today and as temperatures
cool off there could be some patchy fog, mostly in south central
Nebraska.

.LONG TERM...(Tuesday through Sunday)
Issued at 418 AM CDT Mon Aug 19 2019

Expect Tuesday to be dry. There will be a warm front that develops
across north central Kansas. The front moves a little to the north
during the day. This will bring warmer temperatures to the area.
With the dew points in the mid 60s to mid 70s, the heat index values
will be approaching 100 degrees for most of the area and in the 100
to 105 range for the south and eastern parts of the area.

An upper level wave will move through the area Tuesday night through
Thursday morning. There will be a good chance for thunderstorms and
with that there is a chance that some of the storms could become
severe.

The period Thursday afternoon through Saturday there are a couple of
waves that move through the area. There will be some on and off
chances for thunderstorms. With all of the chances for
thunderstorms, the temperatures will be a little on the cooler side.

Saturday night into Sunday will be dry and temperatures will be a
little warmer again.

A cloud deck has moved into EAR this afternoon. Based on current

TAF as expecting it to continue to scatter out as it moves east.
Winds will be southeasterly and a few gusts into the low 20s
