Okay, I’ve posted the radar just to show you what “no migration” looks like. These animations represent one frame per hour from sunset last night through sunrise this morning. You can see the bands of precipitation moving from WNW to ESE, which corresponds to the prevailing winds. No “biological signal” (the peppery blue signature) appears around the radar after sunset; and if you check the velocity, you see that the direction of movement across the radar is either that which I stated before, or a scrambled mess. All signs point to “no migration” last night.
