This is the situation on today's BOM chart too. Of course it is still
too ealy to say but these things seldom follow through two model runs
with 24 hour separation unless they intend to be important.
Even so tomorrow's (or the following day) will be decisive.

Lots of those red mice on yesterday's chart and more again today that
appear to change somewhat this afternoon without going missing
altogether.

Take a look at that blck line about 70 E. that runs from the coast to
the Pole on Wednesday 06:00.
That is an interesting signal.
I don't know the code (yet) but it is signalling until noon Friday.

The next spell is actually a wetter version of this week's:
3 Jul Tuesday@ 18:52
11 Jul Wednesday @ 01:48 and
19 Jul Thursday @ 04:24 is a volcanic one.
Thus, following on from two very wet spells (IF!!) and a previous very
wet couple of spells (which they most certainly were in some places)
things could become very interesting.

The Atlantic chart is showing a marked change after today. It might
even amount to a blocking high. Being the start of a spell today
(Tuesday 3rd) and having the runs taken before it set in, it will take
a day or so to clarify.
With a double High in the North Atlantic, there could be a lot of
tornadoes in the USA. At present the chart just shows them as storms
if at all?
Not sure.
I'll explain it on the blog if I can.
If the High stays focussed on the Greenland-Iceland region, it will
change the character of the spell from wet to dry (in Britain. YMWV.)
For those whose interest in the weather is not pan-galactic like mine,
there has been a severe heatwave in the USA and at the same time
flooding in North America.
Other places suffering too no doubt.
However, so far there have been surprisingly few tornadoes considering
the conditions. Compare:

with

and
>
http://www.spc.noaa.gov/climo/reports/120701_rpts.html
for instance.
(Not that tornadoes couldn't have made up for things in Canada or even
Mexico -though Mexico is more likely earlier in the year when the
solar declination is lower.)
