.DISCUSSION...
*made up scenario for discussion practice*
Hazardous marine weather conditions are expected today as ongoing NW
25-30 kt gusts persist through the next 24 hours. This will create
significant wave heights upwards of 4-7 feet. Additionally, scattered
lake effect rain showers are possible (30-50% chance) in the
vicinity of Grand Island and the eastern UP through this evening.
Confidence is high (>75% chance) that winds will increase out of the
north, becoming gales to 35 kts by tomorrow night. With this, wave
heights will further build between 5-9 ft. There is a 50% chance that
gusts to 40 kts will be present as well. Precipitation is not
expected once lake effect rain showers diminish tonight.
Aviation: MVFR conditions are expected under lake effect
showers/clouds from Traverse City to the east-central UP. The main
concern will be hazardous N to NW winds as 20-30 kt gusts are
expected between 1-3k ft. VFR conditions follow tonight through
tomorrow with diminishing lake effect showers/clouds, however, an
increase in winds is expected with gusts 35-40 kts between 1-3k ft
AGL tomorrow night, mainly after 7pm.
