I. It’s a state divided this afternoon with winter across the northern third of the state (most are in the 30s), seasonable spring conditions central (low-mid 60s), and 70°+ downstate. Unfortunately, we’ll all turn colder tonight and as low pressure scoots east across the Ohio Valley, it’ll help pull a swath of wet snow across the northern half of Indiana after midnight through the predawn hours Thursday. Further north and northeast, a wet accumulation of an inch or less can be expected.
II. We’ll turn cooler to close the week, but with an increasingly sunny time of things, we forecast a very pleasant open to the weekend. High pressure will remain in control of our weather into early next week. Really the only item of interest will be a gusty easterly breeze at times Sunday into Monday. We’ll watch a storm system get shunted south and stay dry here. Overnight lows will remain chilly through the weekend.
III. The next opportunity for meaningful precipitation should arrive the middle of next week (Tuesday-Wednesday) time frame, and even this doesn’t look like a big deal. From this distance, it seems like 0.10″ to 0.25″ will come from that system.
IV. As we look ahead, the relative cold looks to relax as we put a wrap on April and open May. Additionally, we also note the EPS painting much of the northern tier into the Ohio Valley with a drier than normal signal. Sure looks like conditions are finally improving for #Plant18 to get underway in earnest…
Model data continues to show this idea has merit and now we’ll have to handle the individual storms as they come. As we’d expect late in the winter, challenges abound, but this is a pattern that has potential. Can we turn potential into reality? That’s the question that will be answered over the next couple weeks.
The next item on the agenda will arrive Friday afternoon into Friday night. It, too, should spread snow across a portion of the Ohio Valley. With this being in the Day 6 time period, expect fine tuning as we move through the upcoming week.
Finally, a third system will impact the area about this time next week, and it’s this system that appears to be the most significant of the group. Far too early to get detailed, but it certainly warrants our attention.
The overall pattern we’ll “enjoy” over the next couple of weeks is one that’s been lacking for the better part of the past few winters. With blocking in place, storm systems trying to lift into the Great Lakes will be “forced” south and result in an active time of things around these parts- including the east coast, as well, over the better part of the upcoming 10-15 days.
II. We’re hopeful for much needed sunshine Sunday as we’ll be in between storm systems, however any sun that we see won’t last long.
While this is an unseasonably warm pattern (we forecast highs of 50°, or above, 5 out of 7 of the upcoming days, and at least 2 60°+ days), it’s one that will likely result in periods of heavy rain not only next week, but in waves over the upcoming 10 days.
Widespread 10-day rainfall numbers of 3″ to 4″ will be likely in this setup, including locally heavier amounts of 5″ to 6″ in spots. Certainly, if you live near waterways we suggest having a plan in place as it’s not a matter of if, but when flooding takes place in spots across the region with such a setup.
However, big changes begin to take place this weekend and will remain intact for the majority of the next couple weeks. The mean trough position will back into the west while ridging takes hold across the east. This will feature temperatures that will push to above average values and lead to an active and moist southwesterly flow.
Over the upcoming (10) days, temperatures may reach 50°, or greater, on 3 to 4 of those days. Compared to how frigid we’ve been (already had 7 mornings this month with sub-zero lows), this will feel like a heat wave.
