Sat, 20 Mar 2010Philadelphia Weekend Weather Forecast- Sat AM
High pressure will bring a southerly flow of warmer temps to our area on the weekend, in time for the start of Spring at 12:32 today. An approaching low pressure system from the midwest on Monday. Colder temps return for next week.
Sat 3/20: Sunny. Mild. High 71
Sun 3/21: Partly cloudy- a mix of clouds and sun. High 70.
Solar Climate Discussion (Updated 3/9): The sun is beginning to come out of a solar minimum, and there has finally been an increase in solar activity signaling the beginning of Solar Cycle 24. There are several sunspot areas, but the solar flux still hasn't taken off. It's still early in the cycle.
Total Solar Irradiance continues to be about 1 watt/m2 lower than it was during the peak of the last solar cycle, Solar Cycle 23, in April 2000.
As of early March, it looks like the solar cycle is providing the predicted colder than normal temperatures and the El Nino is providing the potent moisture rich southern jet stream. Continue to expect cooler than normal temperatures into the spring.

Sat, 13 Mar 2010Philadelphia Weather Update- Sat AM
The 1 AM rerun of the GFS and NAM models has cut down a bit on the extreme rain amounts compared with last night's models. (By about 0.60 inches) Still heavy rains expected as the rain dynamically develops over us. The heaviest rain is still expected Saturday afternoon.

Fri, 12 Mar 2010Philadelphia Weekend Weather Forecast- Fri PM
The energy from the midwest low is transferring to a new secondary low along the coast, right over our area. The low will be slow to leave due to a closed low upper system and a blocking patter. Both the NAM and GFS are similar and crank out over 3 inches of rain by Sunday morning. The heaviest rain will be on Saturday, especially afternoon.
It appears that lighter rain/showers will continue into Sunday, as the blocked low will remain in the area.
Sat 3/13: Cloudy with rain. The rain will be very heavy. High 50
Sun 3/14: Cloudy with intermittent showers possible. High 52.
Solar Climate Discussion (Updated 3/9): The sun is beginning to come out of a solar minimum, and there has finally been an increase in solar activity signaling the beginning of Solar Cycle 24. There are several sunspot areas, but the solar flux still hasn't taken off. It's still early in the cycle.

Thu, 11 Mar 2010Philadelphia Weekend Weather Forecast- Thurs PM
Low pressure developing in the midwest will deepen as its upper air circulation closes off. With a blocked pattern developing (similar to our last 'storm' here that didn't deliver the expected snow amounts), this storm will linger through the weekend while it induces secondary development off of the coast The latest NAM cranks out very heavy rains on Saturday. Flooding of rivers and streams is likely because the ground is saturated with snow melt.
It appears that lighter rain/showers will continue into Sunday, as the blocked low will remain in the area.
Sat 3/13: Cloudy with rain. The rain will likely be very heavy. High 53
Sun 3/14: Cloudy with intermittent showers possible. High 50.

Wed, 10 Mar 2010Philadelphia Weekend Weather Outlook- Wed PM
A low pressure system will develop in the midwest during the mid week period and deepen as its upper air support develops into a closed low. With a blocked pattern developing (similar to our last 'storm' here that didn't deliver the expected snow amounts), this storm will linger from Thursday through Sunday-- the midwest low will induce development of a secondary coastal low. The GFS is predicting 3-4 inches of rain, with the heaviest rain falling on Saturday. Flooding of rivers and streams is expected because the ground is saturated with snow melt. Stay tuned
It appears that lighter rain/showers will continue into Sunday, as the blocked low will remain in the area.
Sat 3/13: Cloudy with rain. The rain will likely be very heavy. High 53
Sun 3/14: Cloudy with intermittent showers possible. High 50.

Tue, 09 Mar 2010Philadelphia Weekend Weather Outlook- Tues AM
A low pressure system will develop in the midwest during the mid week period and deepen as its upper air support develops into a closed low. With a blocked pattern developing (similar to our last 'storm' here that didn't deliver the expected snow amounts), this storm will linger from Thursday through Sunday-- the midwest low will [try to] induce development of a secondary coastal low. With the transfer of energy to the coastal low and the uncertainty of the exact dynamics in our area, the models have ranged from 4.0 inches of rain to about 1.5 inches with last night's model runs.
It does appear that Saturday will be wet and Sunday may not be much better, it's unclear whether the rains will be torrential or whether there may be extended times of just light rain, drizzle or just clouds. This is a scenario where the details will become more clear by late Thursday.
Sat 3/13: tentative: Rain, showers, possible thundershowers. High 60
Sun 3/14: tentative: Cloudy, some breaks of sun. Chance of some showers. High 58.

Tue, 02 Mar 2010Philly Winter Weather Update- Tues AM
The latest GFS model has the coastal storm closer to Philadelphia than previous runs. This storm, which is expected to develop just to our south and east, will bring a mix of wet snow to our area on Wednesday. The storm track is considerably closer with this model run; this has been the trend with most of the storms this winter. Little accumulation is expected, but expect another nasty day, similar to last Thursday.
I'll update this evening.
