This drier & overall cooler than normal regime continues after wetter, warmer weather back in early April!
The Greenland Block as been the strongest since November here recently in April when we saw low 20s last week.
With such a massive decrease in greenhouse gas emissions & aerosols like soot, snow in the Arctic has turned much brighter white & mega-cities to small cities all over the planet have seen clean air. Air quality in Indiana has improved, as well.
It makes you wonder what this change (which has been underway since late March in a big way) has brought to the weather pattern. We are living a science experiment. More work will need to be done to determine how much of an impact this drastic decrease in aerosols & gas emissions has done to the recent weather world-wide, including here in our area & what (if any) implications it means for the summer outlook.
After 9/11, lack of air traffice resulted in sudden elimination of contrails in the sky, which dropped night-time lows, especically near large metropolitan areas around airports.
I will go digging!
Lyrid meteor shower is tonight! Enjoy while the skies are still completely clear!
They will peak around 2 a.m. at up to 20 meteors per hour. However, overall 11 p.m. to 5 a.m. will see them.
Tonight to the time to view, as clouds will obscure them tomorrow night & the night after.
Highs today reached 50-58 with wind gusts peaking at 31-45 mph over the area.
Dew points tanked to 6-15! This very dry air, with the wind, let to increased brush, grassland, field & forest fire danger.
32-37 tonight will give way to 65-75 tomorrow with strong south-southwest wind developing. Gusts of up to 36 mph are possible.
It appears that we may see a few isolated showers/t'showers along the warm front, so I inserted a 25% POP for Wednesday with increasing clouds with some sun.
Best potential is in north & northeast half of the area.
After a few of these showers/t'showers, some more scattered showers & even a few t'showers will come in tomorrow night as front moves back south as cold front. Also surface low will be tracking southwest of our area, which will lead to some scattered showers.
Lows will run in the 50s.
Best showers coverage will be in the south half Thursday & it will gradually taper from 50% to 30% coverage.
Skies look mostly cloudy to cloudy with highs 60-66 (coolest in the south & far northwest), then falling into the 50s late as strong wind from northeast to north-northeast up to 32 mph commences.
RAINFALL TOTALS look to run 0.05-0.60" (heaviest totals in the south).
With clearing, lows of 35-45 are likely northeast to southwest Thursday night (with north to northeast wind). Some fog is possible, mainly in the north & northeast as moist, cold air moves in off of Lake Erie & Huron, as well as part of Lake Michigan.
Warm front should move back north some Friday.
Wind should be east north of warm front & southeast to south to the south of the front. This will result in big temperature difference over the area from 58 north to 72 in the south & around 68 at Lafayette.
Rainfall is likely Friday evening-Friday night with isolated thunder & strong east winds. Lows will drop into the 50s.
If system tracks farther to the north, then it will be warmer here with severe weather risk.
Rainfall should taper Saturday with highs in the 50s to lower 60s, then falling.
Winds will be strong from the northwest up to 40 mph.
Periodic showers & storms then return April 28-30. Some severe risk is possible over a large area from Iowa to Kansas to Texas to Alabama, northward to Indiana. Core of the highest risk is Iowa to Kansas, Missouri & over Texas & Oklahoma, per current forecast parameters.
