——————————————————————————————————————————
Today we will reach a high in the lower 30s in Helena, while highs in the plains will only reach the single digits and teens. There will be some light snow moving through the state later tonight ahead of the snowstorm Friday.
This is a tough forecast. It's trending more likely that we will see mainly snow in Helena throughout Friday and into early Saturday. However, a few things still concern me that could affect the type of precipitation we see.
1) Most models have a shallow cold air mass advancing southward through the Wolf Creek area into Helena. We have seen hints of this already with fog traveling up the Missouri last night and this morning. But if it full doesn't set in, we could be looking at a wintry mix, similar to what Missoula will see.
2) At the 700 MB level, or about 10,000 feet, warmer air will overrun the colder surface air. Depending on how far north this gets, we could be looking at a bit of freezing rain Friday afternoon and early evening.
