It’s another pretty day across the Tri-State as skies cleared overnight allowing temperatures to drop to the upper 30s in a few locations before bouncing quickly back into the 40s after sunrise. With plenty of sunshine and scattered clouds we’ll head for highs in the upper 60s to near 70 this afternoon. I didn’t mention this on Monday, but the weekend air mass change did reduce the pollen numbers as I expected, and while some sensitive folks may still be dealing with allergic reactions, the amount of pollen floating around is 10 to 20 times lower than last week.
I have been talking about our need for rain and it appears we may be getting what we need, but just in time for the weekend. A large western storm will slowly move our way today and tomorrow with clouds increasing and rounds of showers and thunderstorms developing on Friday, Saturday, Sunday and Monday. Locally heavy rainfall is possible and current model guidance is suggesting that some readers will get 2 to 3 inches of rainfall, but most areas will receive .75” to 1.5 inches. It won’t get us back to normal, but it’s a start. There has only been one-half inch of rain at the Northern Kentucky Airport this month, but we normally get around 4 inches in April…so we’re at only 13% of normal right now.
There may be a few showers before the big weekend event as a weak atmospheric disturbance crosses the Ohio Valley later tonight and early tomorrow. The showers will be light and scattered, so a few of you will wake up with some damp ground and raindrops on your car, but most areas will be dry. After highs in the upper 60s to around 70 today, we’ll be back in the upper 60s to near 70 for Thursday with highs in the 60s as the showers and t’storms hit on Friday.
Weekend temperatures may vary greatly north-to-south as a frontal boundary separates 70-degree warmth near and south of the Ohio River from upper 50s and low 60s north of Cincinnati on Friday. The southern warmth may spread across the area on Saturday with highs in 60s to low 70s, but cooler air is expected to shift back into the region on Sunday and Monday.
I see more rainy weather in the final days of April and heading into May and a pattern that will favor near-normal temperatures, which means little threat for frost or freezing conditions but few days for field and garden work in the next 2 weeks. I expect many landscapers to start running behind in their maintenance operations (cutting grass, etc.) after this weekend because of numerous disruptions from the rain.
In other news, the volcano in Iceland continues to erupt, but the eruption is more lava and less ash and smoke, so after nearly 2 billion dollars in losses, airlines are flying again. The losses don’t include the thousands of businesses worldwide that couldn’t get supplies or ship products because of the lost air travel…and this was just a small volcano. We’re still watch Katla, the big volcano that has erupted the last three times that Eyjafjallajokull (yeah, right…try to pronounce that) erupted. If Katla blows, all bets are off and we can expect multiple billions of dollars in losses, collapsed businesses and serious health implications.
The sun remains unusually quiet and we’re now in the longest streak of days without sunspots in the past 6 months (6 days). That means more cooling and clouds in the months ahead and possibly (the relationship is still being studied) more major earthquakes and volcanoes. Enjoy this gorgeous day!
