Ag Weather Report: 6/9/15

From time to time we like to post some of our AG weather reports here as opposed to our weekly updates via e-mail.  (BTW, if you’re interested in more information around this feature, please e-mail bill@indywx.com).

Rains the past couple of days have been beneficial for many areas that were dry in May.  (Here’s a hint, there’s more where that came from).

2Unfortunately, some of that heavy rain came with hail damage- particularly across northern IN Monday afternoon.

Abnormally dry conditions have continued to shrink over the region over the past couple weeks.   May and early June is a crucial time in setting the tone for the summer/ early fall months ahead.  This, of course, is fantastic news.

10As we progress ahead into the second half of the week, additional severe threats will present themselves.  Similar to Monday, hail and damaging winds are of greatest concerns in our particular Ag-weather viewing area (#IAwx, #INwx, #ILwx, #OHwx).

Day 2- Wednesday

3Day 3- Thursday

4As we move forward, a very warm to hot and humid pattern will settle in o/ the course of the next 7-14 days (and beyond).  In looking at the latest European Weeklies (can’t post here due to licensing issues) the warmer than normal pattern and wetter than normal regime is likely to continue through the rest of the month.  It’s not so much the high temperatures in terms of absolutes, but the combination of wet ground (humid and sultry) and warmer overnight lows that will really help power the warmer than normal period in the coming couple weeks.

6In the shorter term, heat will really expand across the region mid week, including many of the first 90 degree readings of the season for most folks.  The European shows the ridge flexing it’s muscle yet again into early next week.

7A very humid time of things will continue, due to the recent wet times and more rain ahead.  Aside from the storm threat(s) mid week, Friday into Saturday will also prove to offer a smattering of thunderstorms as a cold front moves in and stalls south before returning north Sunday.

Upcoming 10-day rainfall numbers are respectable, including 2″-3″ totals for many, with locally heavier amounts a good bet where storms train.

5Note the wet pattern shown deeper into June off the CFSv2:

wk1.wk2_20150608.NAThe JAMSTEC shows the wet pattern into the heart of the summer (June, July, August) and would argue against any idea of major long-lasting heat for the heart of the summer.

8BTW- for you winter lovers out there, here’s a little something to entertain you.  The JAMSTEC is onboard for another “fun” winter ahead.  Factor in those warm NPAC anomalies and a weakening El Nino into the winter and the stage very well may be set for wintry fun and games…  Long way to go here, however… 🙂

Step Down Process To Cold Before The Return Of Truly Frigid Times…

The past 5-7 days have featured a common “January thaw-” something typically seen in even the coldest Januarys.  The coming 5-7 days will see a “step down” process of colder weather, interrupted by a day or two of milder southwest breezes.  In the longer range, we hold firm on the idea of more sustained cold, and potentially frigid air, setting up shop to open February.

See the GFS track the clipper through the lower lakes this weekend.  This is a mild track for central Indiana and will keep the accumulating snows over the Lakes region, extending into northern portions of the state.  Some light snow will fly here late Sunday night/ early Monday, but accumulations should be minimal.

gfs_ptype_slp_conus2_12

gfs_ptype_slp_conus2_16A brief surge of arctic air will invade early next week and may be accompanied by light snow Tuesday.

gfs_ptype_slp_conus2_21A brief southwesterly flow will allow milder air into the region by the middle of next week, but we caution this will be brief.

gfs_ptype_slp_conus2_29Much colder times loom to open February, potentially with a winter storm.  Obviously with this being in the 8-10 day period, there will be a lot of time to watch the storm potential.  Models have struggled mightily with storms this winter so far.  We’re much more confident on the cold, and potentially downright frigid air at that (still don’t think we’ve seen the coldest air of the winter yet).  Note the GFS sees the arctic highs “lining up.”

gfs_ptype_slp_conus2_41The European ensembles and operational are also keying in on the cold and wintry pattern closing January and to open February:

2The NAEFS and CFSv2 see the colder pattern returning:

wk1.wk2_20150122.NAsfcT

We still think there’s a lot of “winter” left in the coming months.  Many folks enjoy snow Christmas into January, but begin to crave spring in February and March.  This is the type pattern that can be quite “ugly” for spring lovers as colder and snowy weather can push well into the spring months…  (Noted that we still have a lot of catch up to do in the snow department, but we’re not ready to say we won’t make up for “lost time”).

More On The “Typhoon Rule”

Perhaps you’ve heard folks discuss the “typhoon rule” over the past few weeks. What I despise is when people take credit for certain ideas without giving credit where credit is…

Cooler To Open September?

As we move through the next week, we continue to think we’ll cool things off as we wrap up August. We’re not talking about any sort of major unseasonably cool…

Monday Evening Video Update!

This evening’s video covers a potential round of thunderstorms Tuesday morning and takes a deeper look at the mid range.  Yet ANOTHER unseasonably cool blast of air awaits on deck for mid-month and will provide a hint of early fall, per the EC ensemble run below for next week.  This is just one piece of data amongst several pieces pointing towards a big mid-month cool down.  Much more in the video update below!
