Alert Details

The weather pattern is expected to transition from a stagnant dominant southwest flow pattern to a zonal and eventually northwest flow by late week into next weekend. Before this happens, however, a few more days of south to southwest winds ahead of a southeastward-advancing cold front are likely especially in the central and eastern corn-growing region. Winds are not likely to be overly strong, so only Low risks are predicted and rainfall may complicate potential migration events, as well. Low risks are predicted tonight into tomorrow from central Kansas as far north as near Minneapolis, Minnesota and east into southern lower Michigan and far western Ohio. Low risks then focus from Missouri and Illinois and points east tomorrow night into Wednesday especially ahead of a cold front and any associated rainfall near the front. Once the front moves into the southern corn-growing region, mainly near I-70 or the US 36/24 corridors, little to no migration risk is predicted for the balance of the week and into next weekend. A weather system may bring some southerly winds up to near this front late Thursday into Friday but the majority of fields in the southern corn-growing region are either beyond critical growth stages, or will be, once new generations that may arrive would be able to cause damage, thus little to no risk.
