No changes today to our overall forecast pattern. WE have a wet weekend in store, and 3 systems over the next 10 days, with 5 in the next 15 days. It will be a very active pattern into early April.
Very warm and mild today over the state thanks to southwest winds streaming in. Temps will be well above normal. This southwest flow is coming in ahead of a strong cold front and low pressure circulation that moves through tomorrow and Sunday. Rains for the complete weekend period look to be from .25”-1.5”, but we are reserving the top half of that range, from .75” to 1.5” only for areas that see significant thunderstorm action, which should be limited to under 10% of the state, thanks to timing of the frontal passage here. Most of the state will be between .25” and .75”. Coverage of rain this weekend will be nearly 100%. The map above shows cumulative rain totals through midnight Sunday.
We still have a brief dry period from overnight Sunday night through Monday midday. But we do not see clouds break very much. Our next little wave comes through for Monday night through Tuesday mid-morning. Rain totals look a little more impressive this morning for that wave, and we are upping our rain totals to .25”-.66” with coverage up to 80% of the state. The better rain totals may be over the northern half of the state, but we probably should not try and finesse the coverage that closely. Dry for the rest of Tuesday through Thursday.
The third system of this 10 day period begins to push in late Thursday night and has its biggest impact Friday. Rains are pegged in the .25”-1” range with coverage
90% of the state. The biggest change in our forecast comes around day 10, as we see another quick hit system arriving for Sunday the 2nd, with only 12-18 hours’ worth of down time in-between next Fridays rains and the Sunday event. Rain for Sunday the 2nd can be from .25”-.75” but if the system slows in its arrival from the southwest, those rain totals may need to be bumped, and we may have to talk about severe weather, as this system stretches into the extended period.
A final system for our forecast period holds on for the 6th and 7th, with rain totals up to half an inch.
Overall, temps look to be mostly normal to above normal while these rains develop and move through. Soil moisture totals should be seen at “surplus” levels by the time we make it through the first full week of April.
A damp weekend is in store for us as a cold front slams the state Saturday and wrap around moisture holds over the state for Sunday. The threat of widespread thunderstorms for Saturday afternoon looks to be somewhat lower this morning than previously. We still think that SW Indiana can see a line or tow of stronger thunderstorms between sunset and midnight, but with that timing, those thunderstorms are likely not long lived. That also means, while we are keeping our rain totals statewide the same as we have been talking about, the threat of rains in the higher end of the range will be limited to a much smaller geographical area. Rains on Sunday will be more shower based, but still have the ability to produce good totals. For the combined 2-day period, we like rains from .25”-1.5”, with a large part of the state in the half to 1” part of that range. Coverage of rain will be nearly 100%. The map above shows cumulative rain totals through midnight Sunday.
Soil temperatures have been stagnant over the past week in the north, as cold shots have limited the ability to gain significant warmth over the middle of the month. We are still several weeks out from having soil temps suitable for major work there. However, southern Indiana is getting very close to the key 50 degree threshold, and with warmer temps in over the next week, we may be ready to see some slightly more serious field work coming around.
Mostly dry for Wednesday and Thursday, although clouds may be a big player for next Wednesday. Our next strong front and system comes in next Friday midday, the 31st, and will have .25”-1” rain potential with 80% coverage. In the extended period, the active pattern continues, with a strong, severe weather producing system likely coming out of the central plains and across the state for the 2nd through the 3rd. Moderate to heavy rains can be with that as we look for totals of .5”-2” and 100% coverage. Another front moves in around the 6th, this time coming from the northern plains and upper Midwest. That track means we are looking at more gentle rains, with a quarter to third of an inch possible toward the end of the 11-16 day window. The above map is an estimate of cumulative rain totals over the coming 10 days…the pattern is very active indeed!
