Since the last time I looked at Isaac earlier today it remained a weak and rather disorganised system with a large envelope of energy but as of this evening, that energy is beginning toshow signs of consolidating and we knew that once this occured then, look out! Maximum sustained winds are up to 65 mph now and this will cause […]
Zonal pattern evolves with stronger than normal heights over the sub-arctic & subtropics With strong positive heights over the high latitudes and a strong sub-tropical high pressure belt to the south, a zonal flow pattern is now ruling the mid-latitudes with a very active trans-Atlantic storm train. Low no.1 is pushing into the UK right […]
Well in many ways little has changed in the past 24 to 48 hours as Isaac continues to remain a weak storm, However that’s only half the story because in a sense you cannot go by the fact that it’s only a 40 mph minimal storm due to the fact it harnesses a lot of […]
If we strip away the uncertainties in the forecast for now and look at what IS certain.. unfortunately what is certain is that Hispaniola which is a large islands which makes up the nations of Haiti and the Dominican Republic and this island will have to contend with significant rainfall from Isaac as he passes nearby to the south […]
As is often the case when you get clusters of thunderstorms develope over the Las Vegas Valley, it doesn’t take much to flood the city. The desert landscape as well as the amount of concrete means there’s little room for the water to escape once it hits the ground and that was the case during […]
Organisation & Initial Intensity Could Mean Difference Between Heading For East Coast or Gulf As Isaac continues to wax and wane as he enters the eastern Caribbean having endured dry air and wind shear. The same question remains despite what the models are suggesting and that is, when will this storm intensify. I really do […]
As we progress towards September and autumn we have varying influences which play into our weather pattern over the forthcoming 3 months. El Nino being one of them and the likely reason for such a wet summer as well as the cold mode of the PDO and warm AMO. Autumn of course is the transition period […]
With blocking highs over top of the mid-latitudes and up in the high latitudes, a zonal (west-east) flow pattern has developed following the highly amplified pattern across the hemisphere of late. Sandwiched between the blocking high over the subtropical high, a rather active North America to Europe storm train is in place. Note the below […]
Since going to bed some 3 hours ago and now I’m back up.. Isaac has been declared and the latest European run continues to take this into the Gulf as a strong hurricane. The overal track looks more and more likely to be skirting SOUTH of the big islands and perhaps making a direct hit […]
Just when you thought those terrible, torturous 90s and 100s was done with the Plains for another summer you happen to look at the ECMWF and go, OH NO! Yes, the heat which has baked the Great Basin and West this month, a complete reversal to the overall summer of 2012 is returning to the […]
