Friday Morning Notebook: Warmer Times This Weekend…
Happy Friday, friends. We’re still cold this morning, but a look at the change in temperatures compared to 24 hours ago shows the milder trend that will be with us through the upcoming weekend. Highs today will reach the upper 40s and 55-60 Saturday.
Winds will turn strong and gusty out of the southwest this afternoon, noted by the tightly packed isobars (lines of equal pressure) along with considerable mid and high level clouds.
Clouds will lower and thicken Saturday and we may also have to deal with periods of fog, as well. Showers and drizzle will lift into town as the day progresses, especially by afternoon and evening.
We don’t expect heavy rain this weekend. In fact, model data continues to really back off on expected totals. The general consensus is between 0.15″ and 0.25″ across central Indiana.
After a mild Saturday, cooler (but not cold) air will ooze into the Ohio Valley Sunday.
Resurgent cold air will blow into town during the middle and latter portions of the upcoming work week. Highs will return to the 30s with overnight lows in the lower 20s. We’ll likely add scattered snow showers into the mix as well.
Timing:
It’s not until we push into Wednesday afternoon and evening that more widespread snow will move through central Indiana, including Indianapolis.
Periods of moderate to locally heavy snow can be expected through central and north-central parts of the state Wednesday evening, especially between the hours of 3p-7p. This will be a wet snow and though the snowfall intensity should be impressive at times, it’ll have a hard time accumulating from what it otherwise could be if the ground was cold. With that said, we do anticipate snowfall rates to overcome initially marginally cold air and “warm” surface temperatures. Our forecast calls for a dusting to 1″ for the city, itself, increasing to 1″-3″ north of the city- encompassing most of north-central Indiana. Roadways will likely become slushy with wet snow accumulation Wednesday evening.
2.) What at one time looked to be a significant weekend storm now may not even deliver any precipitation at all to the region. A flurry is possible, but most should remain precipitation-free this weekend. Expect a gusty southwest wind developing SB Sunday. Highs around freezing Saturday will zoom into the middle 40s Sunday. Lows Saturday morning in the middle 10s will rise into the upper 20s to around 30 Sunday morning.
3.) A more significant storm system will cut for the Great Lakes early next week and this will deliver gusty showers and embedded thunderstorms. A couple of stronger storms aren’t out of the question. Locally heavy rains can be expected, including amounts of 1″-1.5″ (locally heavier totals).
4.) Cold air will rush back into the region behind the storm and snow showers and squalls are likely by Wednesday.
5.) Longer-term, a real fight is developing on the overall direction we’re heading as February evolves. Analog methods and teleconnections (shown below) would yield bullish cold signals and give hope to winter enthusiasts. However, modeling isn’t in agreement on the wintry ideas. In fact, some modeling is very spring-like as mid-Feb nears. Stay tuned as we try and iron out the details this weekend. Updates will come.
