Alert Details

A quick-moving low pressure system is likely to traverse the United States/Canada border region late this week and into the weekend. A cold front is expected to trail south of the low, and east of the front there is likely to be a corridor of south to southwest winds to high pressure in the eastern corn-growing region. This system is a northwest-flow dominated one, so any period of southerly winds is likely to be somewhat brief and not originating in favorable black cutworm source regions further west into Texas. Nonetheless, with planting progress really ramping up in many areas, migration risks are aggressive and Low risks are predicted mainly west of I-35 Thursday night into Friday and then between I-35 and I-69 Friday night into Saturday as the cold front pushes east. Any flights are likely to be isolated to widely scattered, but could pose a risk to newly-planted corn 2-3 weeks from now. Little to no additional risks are currently in the forecast at this time.
