Weather Alert in Nebraska
Dense Fog Advisory issued September 2 at 1:20AM CDT until September 2 at 10:00AM CDT by NWS Hastings NE
AREAS AFFECTED: Valley; Greeley; Nance; Sherman; Howard; Merrick; Polk; Dawson; York
DESCRIPTION: * WHAT...Visibility one-quarter mile or less in dense fog. * WHERE...Greeley, Howard, Merrick, Nance, Sherman, Valley, Polk, York, and Dawson Counties. * WHEN...Until 10 AM CDT this morning. * IMPACTS...Low visibility could make driving conditions hazardous, including for the Tuesday morning commute. * ADDITIONAL DETAILS...Although at least light fog is likely this morning across much of the Advisory area, the development of truly dense fog, reducing visibility to 1/4 mile or less, will likely be more hit-and-miss in nature...impacting some areas more than others. This will result in widely varying visibilities, including over short distances. Although not all areas will see truly dense fog, enough potential exists for dense fog within enough of the area to justify this Advisory.
INSTRUCTION: If driving, slow down, use your headlights, and leave plenty of distance ahead of you.

Freezing rain is a condition where precipitation which has fallen in the form of
water droplets reaches temperatures which are below freezing and freezes upon
coming into contact
with surface objects. The result of this precipitation is a glaze of ice which
can be damaging to plants and man-made structures. A severe onset of freezing
rain which results in a very thick glaze of ice is known as an ice storm.

Next Topic: Hole Punch Clouds
Hail is a form of precipitation which is recognized by large solid balls or
clumps of ice. Hail is created by thunderstorm clouds with strong updrafts of wind.
As the hailstones remain in the updraft, ice is deposited onto them until their
weight becomes heavy enough for them to fall to the earth's surface.
Hail storms can cause significant damage to crops, aircrafts, and man-made structures,
despite the fact that the duration is usually less than ten minutes.
