The El Nino weather pattern that dominated Toquerville weather since early January, continued much of its influence through May, but has now dissipated and will likely have little affect for the rest of the year. Normal temperatures seem to have returned. Still, May was significantly cooler than last year for both the average high and average low. Precipitation has returned to normal, about the same as last year.
Precipitation = .12 hundredths of an inch. (last year was .14 hundredths of an inch)
Average high temp = 77 degrees. (Last year was 88 degrees)
Average low temp = 51 degrees. (Last year was 60.7 degrees)
Average humidity = 24 percent. (Last year was 23 percent)
Average wind speed was 20 mph. (Last year was 22.45 mph) These figures only represent the average high wind speed. What the numbers don’t tell is that the ferocity and length of the winds was significantly less this May than last.

April Weather Data
April has been a bit of an anomaly, weatherwise. We had no freezing temperatures in March, but on April 6th, it froze in Toquerville. It was 32 degrees and froze tender crops like tomatoes and peppers, it also froze some fruit, though not all. I lost about 90% of my apricots, but not nothing else. Peaches and pears were unaffected.
Avg High = 68 (last year was 70 degrees for April)
Avg Low = 45 (last year was 46 degrees for April)
So temperatures are a little lower this year than last.
Avg Humidity = .33% (last year was 29%)
Avg Wind Speed = 18 mph (last year was 17 mph)
Rainfall = .75 inches, 8.47 inches since January 1st
Last year we received .37 inches during April, and 3.12 inches from January through April. So rainfall for April is double from last year, and to date, was almost triple last year's rainfall.
Toquerville had 8 days with winds of 20 mph or greater. Last year we had 11 days of winds 20 mph or greater.
Temperatures remain below normal. Morning lows are also well below normal. The El Nino weather pattern continues to affect our weather, delivering above normal rainfall, and more southerly winds instead of the stronger northerly winds.

March Weather Data
Toquerville received 2.16 inches of rain in March, 7.70 inches since January 1st, which exceeds our annual average. This amount of rainfall is about triple what is normal for the end of March.
Average wind speed for March was 21 mph, a little above last year. And we had 12 days with winds above 20 mph, about the same as last year.
The average high temperature for the month was 60 degrees, the average low was 40 degrees. For 2009 it was 64 degrees for the avg high and 40 degrees for the avg low.
The average wind speed for the month was 21 mph. The average for 2009 was 18 mph
Average humidity for the month was 37%
The El Nino weather pattern continues to dominate the Toquerville weather. The jet stream tracks far south of its normal position, which brings in these southerly, wet, Pacific storms, thus the increased rain we have received. The El Nino pattern typically continues up to, or into, the month of June.
April 1st is Toquerville’s typical frost free date, which is interesting, because April 1st could be one of our colder days, and nights, of the season.
Interestingly, our last freeze occurred on February 26th. The low temperatures for the month of March was 34 degrees on March 12th. It should be safe to plant any garden crops now.

February Weather
Toquerville received 2.5 inches of rain in February, verses 1.6 inches in 2009.
Rain received so far this year? 5.58 inches, vs 2.75 in 2009, and well above average
Average wind speed for February was 14 mph, verses 10 mph in 2009
Average High temperature for February was 52, 55 degrees was the average in 2009
Average Low temperature for February was 36 degrees, exactly what it was in 2009
Toquerville had 1 fog day, and 1 inch of snow in February.
Average humidity was 47%, it was 42% in 2009
Toquerville received a full 60 more minutes of daylight in February.
The El Nino weather pattern continues to influence Toquerville weather, with the southerly tracking storms continuing to bring rain to southern Utah and northern Arizona. We can expect a greener than normal spring in the hills and desert areas of Washington County, as well as more weeds, and not to mention a large number of the beet leafhopper, which carries the curly top virus.

January 2010 Weather Data
In 2009, Toquerville received 1.14 inches of rain in January.
In 2010, Toquerville received 3.09 inches of rain–almost triple the previous year.
And if February is equal to last year (1.61 inches), Toquerville will have received almost 75% of its annual rain in two months. The pattern bodes well for a good water year.
In 2009, the average high temperature for January was 51.26, and the average low 32.97.
In 2010, the average high temperature for January was 48.74, and the average low 32.84
In 2009, the average wind speed for January was 17 mph. The average wind speed for January 2010 was 11 mph.
Toquerville also had one fog day, January 23rd.
Average humidity for January 2010? 49%
So January 2010 has been wetter and cooler than 2009, and that makes sense, more cloud cover, more rain, less radiation reaches the ground, thus cooler temperatures.
And we are in an El Nino pattern, so Utah should receive more rain than normal, more storms come from the south, which means less wind for Toquerville, which is exactly what we had.
Toquerville also received 40 more minutes of daylight in January.

January Weather and Rain
Although Toquerville receives about 7 inches of rain each year, the lion's share of that moisture comes during the months of December, January and February; the balance being more or less evenly scattered through the remaining nine months.
In January 2009, Toquerville received hefty amounts of rain during a four day period in late January (Jan 23-27), and in 2005 Toquerville received heavy rain in January that caused flooding along Ash Creek. Consistent with this pattern, Toquerville also received heavy rain this January. From Monday January 18 through Saturday January 23, Toquerville received 2.44 inches of rain, below are the daily totals:
Monday = .50
Tuesday = .39
Wednesday = .15
Thursday = .93
Friday = .33
Saturday = .14
The Thursday .93 inches of rainfall is the highest single day rainfall in the three years I've been recording data, and the weekly total of 2.44 is well above any previous weekly total over the past three years. So assuming Toquerville receives 7 inches of rain again in 2010, it has already received almost 40% of its annual rainfall.
This weather is a result of the El Nino weather pattern caused by higher than normal warming of the Pacific Ocean water off the coast of Peru. El Nino causes the jet stream to drop well down into southern California and northern Arizona, allowing warm, moisture laden storms to come ashore in southern California and affect Arizona, Nevada and Utah in an unusual way. Meteorologists reported one of the lowest barometric pressures ever seen off the coast of California this past week. And on Thursday morning (Jan 21, 2010) Salt Lake City recorded the lowest barometric pressure reading--ever. That low pressure drew up the moisture from the south and doused the state with large amounts of rain and snow. In an El Nino year, Utah receives higher than normal amounts of rain and snow.
Although Ash Creek, Laverkin Creek, and the Virgin River were all running higher than normal, no flooding occurred. Because the 2.44 inches of rain was spread out over a six day period, with periods of no rain in between, the soil was able to absorb much of the water and prevent flooding.
The prolonged, deep soaking we received this week is ideal for trees, pecans, yards and garden soil. Unfortunately, it also probably insures a bad infestation of the Beet Leafhopper, and another bad year for Curly Top Blight. The Leafhoppers thrive in the hills during wet Winters and wet Springs, then move down into the valleys when the hills dry out in the spring, and our gardens get going.

Observations
1. When the jet stream comes vertically down the state of Utah, Toquerville will always get high winds out of the north.
2. If a barometric low is situated to the east of Toquerville (eastern Utah to western Colorado) we will almost always receive high "canyon winds" from the north or northeast.
3. If a cold front moves through, Toquerville will always receive high winds for at least a day or two.
4. High winds usually last two to three days.
5. There are very few days of the year we receive no wind (two days in 2009)
6. We almost always have a wind over 10 mph, if even only for a matter of minutes, often early in the morning hours, or frequently in the mid-afternoon. Unless a cold front is moving through, or the jet stream is overhead, these winds only last a short time.
7. Toquerville may experience high temperatures over 100 degrees, but unlike most other southwest areas, the high is not reached until early afternoon. And, unlike most other southwest areas, Toquerville begins to cool off between 2-4 pm; thus giving Toquerville only short periods of high temperatures during summer months.
8. The Toquerville summer evenings are not typical of southwest desert areas because Toquerville evenings typically are cool and pleasant. Toquerville only had 37 days with night time lows above 70 degrees, and no night time lows above 80 degrees.
9. St George receives far more wind from the south than does Toquerville, and Toquerville receives far more wind from the north than does St George, though only 19 miles apart.
10. The length of the day (sunlight hours) is affected more by the sunset, than by the sunrise. Over the course of the year, the sunset time changes more than does the sunrise.
