WeatherTiger Mid-Day Model Update for August 25th

HEADLINE: 12z GFS WETTER FOR MOST OF THE CORN BELT…

North America: The 12z GFS is a little drier in the corn belt with the first round of rainfall through late Saturday, as Laura edges a little east on this run and makes landfall early Thursday morning near the TX/LA border. Rain totals from the second round of rainfall late in week 1 and early in week 2 are similar, although this run has shifted the last round of rainfall back 12-24 hours into Wednesday. Week 2 trough is a little stronger and further west, with another round of Midwest rain arriving around day 11.

A separate tropical forecast for Laura is forthcoming this afternoon.
