storm #1 - 12-05-99

Residents of northern missouri went to bed last night thinking they would
wake up to rain, changeing to snow during the afternoon, and they were told
snowfall totals were to be less than an inch. However, things changed
rapidly last night, the storm system did not weaken as was thought, and if
anything got stronger. The change over went through northern missouri's
harrison county arround 300am. and as 330am I took my first ham->nws relay
of the storm, with a mobile report of heavy snow on I-35 between bethany
and egaleville, the storm was clearly going to give us more snow that
anyone thought. Mike Wasleski and I issued a forecast calling for 2-5"
inches of snow through out the area from kansas city to bethany to
kirksville. At just after 400am the rain changed to moderate sleet here,
and roadways started to become slick. At this time, I started my first
attempt to go to bethany, this ended some 45mintues later when I turned
arround near jamesport (10miles sw of trenton) due to heavy snow, near zero
visb. and very slick roads. It was nearly 6AM before I got back into
trenton, so my little 20mile (10m both ways) took me nearly 2hours. Upon
ariveing back in trenton we had heavy snow, visb down to about 1/4mile at
best. roads in the city of trenton were snow covered at extremely slick.
after giveing a phone call or two to brief some people on the storm system.
I took a measure of the snow and, at 630am, we had 2" inches of snow. I
started driveing arround town to check on roadways, once the sun came up
and snowplows got out in full force, the roads started to improve greatly.
at 830am, we started picking up the heaviest snow we saw from the system,
this band lasted about an hour. This band started mixing with snow grains
which kept our trenton total down. The storm started to wind down arround
11am central time, but not before dumping over 5" of snow on the area. some
of the hardest hit areas were northern davissee county, southern harrison
county, northwestern grundy county and all of mercer county.
