April 30

Today started out a little damp, but became very nice for the most part. Not too clear out but the clouds have had many breaks in them. Many cumulus humilis clouds, now we are seeing alto stratus, possibly congestus clouds, and cirrus clouds. This indicates instability and moisture in the air. I expect we can see rain tonight or tomorrow.

Temperature: 68°F
Dew point: 40°F
Humidity: 37%
Pressure: 1007.5 mb
Wind: W 7 mph

 The surface map for today indicates the start of the (last) cold snap. We have a low pressure system in our region in which we were mainly in the southern portion of, which is explains the warm weather, due to the warm air rotating counter clockwise around that low system from the south. But now as that system dies out, the jetstream will change, bringing a cold continental polar air mass south over the next few days, possibly bringing snow or just colder rain.

 The dip over Saskatchewan shows that airmass moving south.

The moisture over the mid states will follow the jetstream up into our area, dumping that moisture on us. You can also see the mid latitude cyclone forming from the current low pretty neat.
