Here's a current look at water vapor across the area on this Monday morning. Notice we've got more greys in the area than over the weekend; mid-level moisture has begun to increase which is why we've got some high-level cirrus in the area this morning.
Also, here's a look at precipitable water values across the area. Notice a relative minimum across the GTR right now; I'm expecting this to continue throughout today and therefore I'm not expecting any rain chances today. Notice moisture pooling to our north in association with a frontal boundary, but this front is losing steam and should not make it much farther south than its current position.
Models have agreed that our low-level flow will be easterly throughout today and Tuesday, so gradual moisture return is likely but the overall moisture content should remain limited as the moisture is getting modified.
By the week's end, we'll see a more southeasterly and southerly low-level flow, and moisture should be higher relative to earlier in the week. This will allow for higher rain chances as well as a frontal boundary tries to approach us from the northwest.
BOTTOM LINE:
Dry weather stays with us for today and Tuesday, but isolated showers are possible for the middle of the week. I think a little bit higher rain chances comes in here for Friday - Sunday in association with a slow-moving front.
