I have a weather related question for you. I have had several friends mention they didn't sleep well last night and we were wondering if the barometric pressure changes from Hurricane Florence are affecting Indiana and our sleep patterns. Or are we all totally off base with this assumption?

-Crystal C.

Hello Crystal!  Florence is lowering our pressure a hair by bringing in more humid air from the northeast & east.  Warmer, more humid air is more buoyant.  With it being lighter, it lowers the surface air pressure some compared to dry, cool air, which is not so buoyant.  That is really the only way Florence would have affected our weather in the past day (other than bringing the east to northeast wind).  Even this evening, dew points ranged from near 60 in the west to 70 in the east as more humid air was being pulled in from the east from Florence.

The air pressure may lower a bit more as the center passes the Appalachians & we see a continued rise in humidity with highs in the 85-90 range.

Otherwise, there is not a big effect from the system.

Right now, weather/seasonal issues affecting people include high pollen count (specifically from Common & Giant Ragweed), dust in the air from the start of the harvest, increasing mold spore count (as wet soils' & leaf litter molds activated from Gordon rains & the foggy, dew-laden mornings, release spores), shortening daylength confusing our summer-established sleep regimes & the high amount of sunlight in these mostly sunny to sunny days.  At night, with the calm conditions & inversions forming, allergens have been getting trapped in this inverson with frequently nightly fogs.  This has only exacerbated allergies, especially in sensitive individuals.

Thank you for your question Crystal!
